Design and Implementation of Real-time Momentum Wheel Control System Based on FPGA

As a significant actuator, the momentum wheel is widely used in the satellite attitude-control. This paper presents the design of the control system based on FPGA for the demand of high precision and low power consumption of the momentum wheel control system. Integrate momentum wheel rotation speed measurement, commutation control and PID speed control algorithm in FPGA logic. The system test verified that the system can achieve a center speed of 3000r/min, a stability of \pm 1r/min, and can be adjusted within a range of \pm 1000r/min. The system can realize the demand for high-precision attitude control of satellites.
