Abstract

In this paper, a H_infinity controller based on sensitivity function is designed after the system analyzing and model building on magnetic bearing of reaction flywheel which has an external rotor, a large moment and a small span. The simulation results of PID and H_infinity controller are given also. The results indicate that the H_infinity controller can provide more robustness, higher control accuracy and higher ability of disturbance limiting than PID controller.
