Abstract:
Aiming at the characteristics and the request of reaction flywheel, a twoloop variable structure control method was designed according to the variable structure control theory. It was based on the system analyzing and modeling on brushless DC motor (BLDCM) of Magnetically Suspended Reaction Flywheel (MSRW). The design of the controller satisfies reach qualification. The simulation results prove that the new control method has the advantages of improving system dynamic response, reducing steadystate error and invariance to the disturbances compared with the PID controller, chattering and reducing steadystate error compared with the singleloop variable structure control method. This control method improves MSRW control system’s dynamic response and disturbancerejection ability, which is important for realizing the high precision and high steady satellite attitude control.
