For nonlinear system with single degree of freedom active magnetic bearing the open-loop instability,the model reference adaptive PID control algorithm is applied to the controller of active magnetic bearing system.Simulation is conducted through the S-Function function block of the MATLAB software.The results show that the response speed,the dynamic and steady-state performance of the system is ideal,and the rotor can realize stable suspension.In case of disturbance has strong resistance to interference and recovery capability,and good robustness.%针对单自由度主动磁悬浮轴承系统的非线性、开环不稳定性特点,将模型参考自适应PID控制算法应用到主动磁悬浮轴承系统的控制器中,通过MATLAB软件的S-Function功能块进行仿真,结果表明:系统的响应速度、动态性能、稳态性能均较好,转子能够实现稳定悬浮,在有扰动情况下有较强的抗干扰及恢复能力,鲁棒性强.
