摘　　要：针对磁悬浮列车传统PID控制器的不足,通过分析PID控制器的特点,引入系统误差参数,设计出非线性PID控制器,实现悬浮系统稳定悬浮。仿真和试验结果表明,该非线性PID控制器结构简单、易于实现、响应快、无超调、精度高、抗扰动能力强,控制性能明显优于传统PID。Aim to the shortages of traditional PID levitation controller for maglev train, PID controller characteristic was analyzed, and nonlinear P1D controller considering system error parameters was designed to realize system stable levitation. Simulation and test results showed that the nonlinear PID controller had the advantages such as simple structure, easy for realizing, quick response, high precision and strong anti-interference ability, obviously better than the traditional PID controller.
