By using the hybrid-sensitivity scheme, a H〓 controller is devised and H〓 control in the new MB system is compared with that of PID control. The standard bi-state magnetic bearing amplifier have some disadvantages such as high current harmonics, low reliability and the current mode switching for tri-state amplifier is expounded.
