摘要
提出了主动磁悬浮轴承的一种变参数PID控制方案,给出了控制器参数的整定原则。在MATLAB的SIMULINK环境下构建控制系统模型,用S-function编写变参数PID控制器的参数变化规则模块和磁悬浮轴承的非线性模型,并进行了动态仿真。仿真结果表明,这种变参数PID控制器对磁悬浮轴承有比较好的控制效果。
This paper presents a variable parameter PID controller applied to the magnetic bearings system. The parameters turning principle of this controller is proposed. The control system is simulated by the simulink of MATLAB; the parameter turning module and the nonlinear model of the magnetic bearings are realized by S-function. The simulation results show that the control effect of the variable parameter PID controller is better than that of the conventional PID controllers.
