Control System Design and Modeling for Compensation Wheel
For the defects exist in recent design method of compensation wheel, the working speed is raised to reduce the mass increment and improve the bearing lubrication. By the means of new thought, a double closed loop controller is proposed which uses high-authority control (HAC) and low-authority control (LAC) to guarantee the speed of response and steady-state error for a good performance. The models of encoder, friction torque and compensation wheel are established in Simulink. Based on the requirement of attitude stability and pointing accuracy of a satellite, the controller parameters are synthesized. In the section of simulation, results reveal that the compensation system has a satisfied performance.
