Abstract

Magnetic bearings have been used in flywheel energy storage systems for improving their performance due to the main advantage of contact-free operation.However, the gyroscopic coupling, parameter coupling and imbalance force affect the operating performance and stability of an magnetic suspended flywheel energy storage system with asymmetric rotor,therefore, a cross feedback based control method is proposed. Firstly, the dynamic model of a radial four-degree-of-freedom active magnetic bearing rotor system is derived.Next, a novel cross-feedback-based modal decoupling controller is designed for vibration suppression caused by gyroscopic coupling, parameter coupling and imbalance force.Better performance is obtained through comparing the decoupling performance, control performance and disturbance rejection performance with a traditional decentralized PID and a cross feedback controller.
