摘　　要：根据奇异摄动法,建立了混合磁悬浮系统非线性动态数学模型,并根据控制器参数的整定原则,提出了混合磁悬浮球的一种变参数PID控制方案．在MATLAB的Simulink环境下用S- Function编写参数变化规则模块,所进行的动态仿真结果表明,变参数PID控制器无论在上升时间、超调量,还是调节时间上都明显优于传统的PID控制器．The nonlinear dynamic models of the hybrid magnetic levitation ball system is examined, where the singular perturbation method is used. According to the parameters adjusting principle of the controller, a variable parameter PID controll scheme applied to the hybrid magnetic levitation ball system is proposed. The module of pa- rameter adjusting are realized by S - function based on the simulink tool of MATLAB. The simulation results show that the control effect of the variable parament PID controller is better than that of the conventional PID controllers even in the rise time or the overshoot and the adjust time.
