摘要可控磁路式永磁悬浮系统具有强非线性、控制难度大等特点。根据该永磁悬浮系统的特点，本文设计了一种由角度环和位置环组成的串级控制器。利用该控制器对永磁悬浮系统进行位移外扰仿真和实验。实验结果表明应用该串级控制器，系统具有良好的鲁棒稳定性，当给系统一较小阶跃外扰时，系统可以在短时间内跟踪输入位移信号，达到新的稳定悬浮状态。

Abstract：Permanent magnetic suspension systems with controllable magnetic circuit have characteristics of strong nonlinearity and large difficulty in control. According to the characteristics of a permanent magnet suspension system, a cascade controller composed of an angle loop and a position loop was designed here. A permanent magnetic levitation system was simulated and tested with this controller. The test results showed that the system has a good robust stability; the system can track an input displacement signal within a short time and reach a new stable suspension state when a smaller step external disturbance is exerted on the system.

Key words： permanent magnetic suspension controllable magnetic circuit cascade control
