摘要
A hybrid suspension system with permanent and electric magnets was designed, and its mathematical model was derived. A controller was designed based on zero power control strategy, i. e. the current in electromagnets is maintained at about zero. Simulation shows that with this controller the system realizes stable suspension with large air gap and low power consumption. Compared with the system based on fixed gap control strategy, the hybrid suspension system based on zero power control strategy consumes much less energy with a little loss in suspension stability, although both of the systems provide stable suspension with large air gap.
