    Overview:
    The Magnetic Levitation System (MLS) is composed of an LED light source, an electromagnet, an optoelectronic sensor, amplifier module, an analogue control module, data acquisition card, and a steel ball, etc. Its structure is simple, yet the control effect is very intuitional and interesting. One can easily levitate one or more steel balls in a steady-state position and keep them floating. This system synthesizes main experimental contents in control area and satisfies many experiment requirements such as automatic control, control theory, and feedback system, etc, which are suitable for UG or PG course designs and algorithm research as well.

    Control Principle:
    • The MLS is a typical non-linear open-loop unstable system. By passing a certain amount of electric current through the electromagnetic winding, it will generate an electromagnetic force. By regulating the electric current in the circuit, the electromagnetic force can be adjusted to be equal to the weight of the steel ball, thus the ball will levitate in equilibrium state. However, this state is an open-loop unstable equilibrium; it is because the electromagnetic force between the electromagnet and the steel ball is inverse proportional to the square of the distance between them. Once the equilibrium state is slightly interfered (For instance, pulsation of the voltage across the electromagnet winding, or vibration around the system, etc), the ball will drop or be gripped by the electromagnetic winding, so the system has to be a closed-loop control system.
    • The measuring equipment, which is composed of an LED light source and a sensor, can detect the variation of the distance between the steel ball and the electromagnetic winding. When the ball is dropping due to interference, the distance will increase. The sensor detects the variation of light intensity and generates a related signal. After the adjusting process by the controller and the magnifying process by the amplifier, the control electric current passing the electromagnetic will increase, the steel ball will be attracted back to the equilibrium position.

    Laser SensorClass 2 Red Semiconductor Laser, 655nm, 1mW max

    Overview:
    Magnetic levitation is a classical technology in mechatronics. It combines electromagnetism and electronics technology, control technology, signal processing, mechanics, and dynamics. The technology is widely used in many industry fields such as magnetic levitation train, magnetic suspension bearing, miniature transmission equipment, measuring instrument, robotic wrist, magnetic levitation educational system, etc. The Magnetic Levitation System (Model: GML2001) from Googoltech provides an ideal experiment platform for research and tutorial for undergraduate and graduate students studying classical control theory and modern control theory. Apart from its modern designed appearance, laser sensor is also applied as feedback signal to measure moving distance of the floating ball accurately. In addition, the Magnetic Levitation body (Model: GML2001A) can be provided as a standalone experimental device for any third party or self-designed controller.

    System Features:
    • Students can thoroughly comprehend PID tuning, root locus tuning, frequency domain method tuning, status feedback control method with Matlab software platform experiment course.
    • Via optional analog control system, by observing and comprehending the structure of control system and the characteristic of driving module, students can construct embedded magnetic levitation controller by combining the analog control system with DSP, ARM, MCU, etc. The embedded discrete control algorithm can be perfected by comparing control results.
    • Students can select components such as photoelectric, ultrasonic, infra-red distance detecting sensor to build up the magnetic levitation body; and construct complete magnetic levitation system with self-designed embedded controller.
    • Laser sensor is used as feedback signal. Through the experiments, the non-linearity of the system can be directly viewed by the distribution of the electromagnetic field.

     

    Control Principle:

    • When the ball moves up and down vertically under the electromagnet, the laser sensor right below the ball detects the distance between the apex of the ball and the lowest part of the electromagnet. It converts the voltage signal to the controller. The controller calculates the output current level of the electromagnet coils. The emerged magnetic force can levitate the ball under the electromagnetic stably in any arbitrary position within the range.
    • Due to the characteristic of the mathematical modeling of the device that the composed unit is unstable without the controller, a corresponding controller must be designed to stabilize the system. As the linearization has to be carried out around a non-zero operating point, it is therefore very challenging.

     

    Experiment Content:

    • Based on Matlab platform
    • System modeling experiment and analysis;
    • PID tuning & PID controller design;
    • Root locus tuning, frequency domain method tuning, and status feedback.

                  Overview:

                  The 3DOF helicopter simulator, which has 3 degrees of freedom in rotation, is a new educational product developed by Googol Technology. It is not only of great value in the field of aviation and space flight research but also ideal to evaluate feedback strategies, such as PID, LQR, H infinity, fuzzy, neural net - any one you wish to implement. As one of the newly recommended products, its hardware system is matched with a textbook which covers classical control, modern control and dynamic modeling experiments in details, so it offers the students and researchers in the fields of automation and mechatronics a unique opportunity to control the pitch and yaw of a simplified helicopter.

                  Structure and Operation Principle:

                  The 3DOF helicopter simulator consists of a pedestal upon which a long arm is mounted. The arm carries the "helicopter body" on one end and a counterweight on the other. The arm can also tilt about an "elevation" axis as well as swivel about a vertical (travel) axis. Optical encoders mounted on these axes allow for measuring the elevation and travel of the arm. The helicopter body mounted at the end of the arm is free to pitch around the "pitch" axis. The pitch angle is measured via a third encoder. Two motors with propellers mounted on the helicopter body can generate a force proportional to the voltage applied to the motors. The force generated by the propellers causes the helicopter body to lift off the ground. The counterweight can reduce the power requirements on the motors; it is adjusted so that the effective mass of the body is proper. All electrical signals to and from the arm are transmitted via a slip-ring in order to eliminate the possibility of tangled wires and reduce the amount of friction.

                        Introduction:
                        • The Inverted Pendulum System (IP) is a classical experiment device for undergraduate and graduate students for learning control algorithm. Rotary motor is usually used and linear motion is achieved by indirect conversion of synchronous belt. The all new Direct Drive Motor Inverted Pendulum System by Googoltech using advanced cylindrical linear motor for direct driving. It gets rid of intermediate transformation segment of indirect control mode. The modeling process is thus more accurate and reliable. This new type of direct drive mode is modern and can stimulate the curiosity as well as learning passion of the students.

                        System Characteristics:
                        • Cylindrical linear motor and advanced position detection technology are adopted so that the system structure is simple. Students can better understand the motion principle of electromechanical system through learning.
                        • Students can carry out PID, root locus, LQR and other controller design with the attached Matlab examples. They can feel the enchantment of automatic control technology.
                        • When implementation of control algorithm in Matlab environment is completed, students can set up their own DSP, ARM, FPGA, MCU and other platforms for higher efficiency real-time control of the inverted pendulum.

                         

                          Control Principle:

                          • DDR Linear Inverted Pendulum is a typical single input double output system with acceleration of motor as input, swinging rod angle and motor position as outputs. By detecting and sending back angle of swinging rod and motor position to the controller, a suitable acceleration control generated by the controller is transferred to the motor to keep the swinging rod in vertical upward state. The motor is also kept stably within the set balanced position. The below diagram is the system diagram of the DDR IP based on LQR control algorithm.

                              The Four-Rotor Hover Vehicle consists of motors with air screws, encoders, drive modules, motion controllers and slip rings, etc. It is a highly coupled multiple degrees of freedom system. Different flight controls such as elevation and depression, inclination and hovering of the vehicle can be achieved. The system is suitable for undergraduates, postgraduates and control theory researchers to carry out verification and research of control theory such as optimal control, robust control, etc.

                              The four-rotor hover vehicle is powered by the 4 airscrews of the motors placed at the gumball shaft. The front, left and right motors drive the corresponding airscrews to fulfil the elevation and depression of the vehicle, the left and right motors drive the corresponding airscrews to overturn the vehicle, while the rear motor drives the corresponding airscrews to realize the navigation of the vehicle. The 3 encoders which are installed on the platform detect the different aviation statuses of the vehicle and form a closed loop system, thus fulfil precise positioning of the elevation and depression, tilting and hovering of the vehicle. Slip rings are installed in the base of the vehicle so that the wirings will not tangle up when the vehicles rotate freely. It also helps to reduce friction.

                                  The planar inverted pendulum series adopt an open architecture control solution and a modularized experiment platform. With XY table and 2-DOF robot arm module as the base platform, adding a 2-DOF ball joint, an one-stage or a two-stage inverted pendulum is developed to provide a more challenging research and experiment platform. A planar inverted pendulum simulates more closely the control and visual effect of an inverted handstand of an acrobat or the launching position control of a missile or rocket.

                                  The 3DOF helicopter simulator, which has 3 degrees of freedom in rotation, is a new educational product developed by Googol Technology. It is not only of great value in the field of aviation and space flight research but also ideal to evaluate feedback strategies, such as PID, LQR, H infinity, fuzzy, neural net - any one you wish to implement. As one of the newly recommended products, its hardware system is matched with a textbook which covers classical control, modern control and dynamic modeling experiments in details, so it offers the students and researchers in the fields of automation and mechatronics a unique opportunity to control the pitch and yaw of a simplified helicopter.

                                  Structure and Operation Principle

                                  The 3DOF helicopter simulator consists of a pedestal upon which a long arm is mounted. The arm carries the "helicopter body" on one end and a counterweight on the other. The arm can also tilt about an "elevation" axis as well as swivel about a vertical (travel) axis. Optical encoders mounted on these axes allow for measuring the elevation and travel of the arm. The helicopter body mounted at the end of the arm is free to pitch around the "pitch" axis. The pitch angle is measured via a third encoder. Two motors with propellers mounted on the helicopter body can generate a force proportional to the voltage applied to the motors. The force generated by the propellers causes the helicopter body to lift off the ground. The counterweight can reduce the power requirements on the motors; it is adjusted so that the effective mass of the body is proper. All electrical signals to and from the arm are transmitted via a slip-ring in order to eliminate the possibility of tangled wires and reduce the amount of friction.

                                    • When the ball moves up and down vertically under the electromagnet, the laser sensor right below the ball detects the distance between the apex of the ball and the lowest part of the electromagnet. It converts the voltage signal to the controller. The controller calculates the output current level of the electromagnet coils. The emerged magnetic force can levitate the ball under the electromagnetic stably in any arbitrary position within the range.
                                    • Due to the characteristic of the mathematical modeling of the device that the composed unit is unstable without the controller, a corresponding controller must be designed to stabilize the system. As the linearization has to be carried out around a non-zero operating point, it is therefore very challenging.

The semi-physical simulation is to connect the mathematical model, the solid model and the actual equipment of the system to form a simulation system. When simulating this system, the physical intervention in the analog loop requires that the simulation be performed on-the-fly. The simulator must acquire dynamic input signals under the conditions of synchronization with the real system and generate dynamic output responses in real time. The experiment box is free to design a variety of circuits with various components, and the Matlab software platform can be used to simulate experimental phenomena and results in real time. The experimental box design is compact and suitable for large-volume placement in the laboratory to meet the experimental needs of the team.
