摘　　要：根据混合磁铁的动力学方程和电磁铁绕组的电路方程,建立混合悬浮系统的动态模型,针对系统的开环不稳定性以及系统受到扰动时传统PID控制参数难以实时保证系统性能最优或接近最优的问题,设计了基于二次型性能指标的参数优化自适应PID控制器。仿真结果表明,在系统受到扰动时,该控制器能够实现控制参数的自适应调整,保证系统快速回到平衡位置,提高了系统的抗干扰能力和稳定性。According to hybrid magnets＇ dynamic description and electromagnet＇s circuit equation, the hybrid suspension system model was built. In order to solve the problem that ordinary PID controller＇s parameters was hard to maintain optimal values with disturbances＇ occurrence of the instable system, parameters-optimized adaptive PID controller based on quadratic performance index was designed. The simulations indicated that the proposed controller improved system anti-interference and stability, achieving controller parameters real-time adaption when disturbances occurred.
