- 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.
- 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 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.
System Features:
- ardware platform based on PC and DSP-based motion controller.
- Experimental entity platform provided for the major of aviation.
- Comprehensive experiment kit, covering the dynamic modeling, classic control experiment, modern control experiment, optimized control experiment and intelligent control experiments. Users can select relevant algorithm for the experiment and teaching needs of various courses.

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.

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.
- Based on analog control system
- PID tuning & analog control experiments.
Matlab Control Interface:
- Use Root Locus Control as an example (support Matlab version 2012b or above)
Control Configurations:
- Digital Control
- The standard model (GML2001) uses PCI Data acquisition card to communicate with the Magnetic levitation system drive.
- Analog Control
- The analog control box model GAES1001 directly uses amplifier to control the system by two control schemes: current control and voltage.
- Any other third party or self developed controller.
