Servo control system for quick response magnetic suspension control torque gyroscope frame

A magnetic levitation control torque gyro framework servo control system for rapid response includes a magnetic levitation control moment gyro framework, a framework servo torque motor, an angular position sensor, a DSP digital control device that includes a current sensor, interface circuits for current and angle position sensor, a frame servo control system controller and a nonlinear differential tracker. The tracker calculates the angular rate of the servo system, and gets the difference with the granted rate to send into the controller, to enhance the accuracy of the rate of the system. The invention introduces the non-linear differential tracker, to realize the point-to-point differential track on the angular position of servo system, avoid the random noise that is fused during the process of getting the angular signal from the differential, improve the accuracy of angular rate, accelerate the response speed, and save the use of the system.
