| 摘 要： | 建立了由永久磁铁和常导线圈构成的混合悬浮系统及其数学模型．基于零功率控制策略，即保持电磁线圈中电流近似为零，设计了使系统稳定的控制器．仿真结果表明，这种混合式悬浮系统可以通过采用零功率控制策略实现大气隙、低能耗的稳定悬浮．与定气隙控制策略比较，两者均能实现大气隙稳定悬浮，基于零功率控制策略的控制系统能耗明显减少，悬浮稳定性稍有下降．

| Abstract: | 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. |
