A Method of Suppressing Unbalance Vibration of AMBs Based on Flux Feedback Control

In this paper, an unbalance vibration suppression method based on flux feedback control strategy is proposed. The air gap flux is obtained from an improved flux observer. The principle of generalized notch filter is analyzed in detail and the transmission matrix parameters are reasonably designed so that the system can keep stable in a wide speed range. The simulation results show that adding generalized notch filter algorithm into the control system can restrain the vibration force caused by the mass unbalance of rotor during rotation.
