Abstract :
Reaction wheel is an important executive component of satellite attitude control system. The disturbance, which is caused by the reaction wheel with a current controller, greatly influences the accuracy and stability of satellite attitude control system. To solve this problem, the idea of speed feedback compensation control reaction wheel is put forward. This paper introduces the design and performance comparison of satellite attitude control systems, which were separately based on current control reaction wheel and speed feedback compensation control reaction wheel. Analysis shows that the speed feedback compensation control flywheel system may effectively suppress torque fluctuation. Simulation results indicate that the satellite attitude control system with speed feedback compensation control flywheel has improved performance
