Research of Variable Structure Control System of Supported Rotor System

The magnetic supported system in the new type of Gyro is designed according to the characters of magnetic supported system. A method using additional compensating coil is proposed. It is proved that the rotor suspended in the system is stably suspended. The control mathematic model for Gyro´s rotor supported system is founded. The system is characterized by its instability psila nonlinearity ldr In this paper psila a variable Controller is designed. On the basis of common control theories, a Variable controller is designed. The simulation results show that our controller is characterized by fast dynamic responding, strong robustness. The results show that the controller can keep every state parameter in the rotor magnetic supported system to trend towards its designed value.
