Design and Comparative Analysis of Control Laws for Control Moment Gyroscope

Control moment gyroscope is a commonly used controller in an attitude control system of spacecraft.Control methods research of control moment gyroscope can provide necessary theoretical basis for developing attitude control system of spacecraft.In this paper,three control laws for control moment gyroscope by successive loop closure/PD,pole placement,full state feedback linear quadratic regulator,are designed respectively,and the validity of the three methods are confirmed by controlling an actual system to meet the expected control target.The control performances of the methods are compared and analyzed,and the results of the three control strategies have provided theoretical guidance for further studies in this system.
