摘要
磁悬浮系统是一种非线性、不稳定系统。采用PID控制时,动态性能较差,控制效果不理想。为了获得控制效果较好的控制器,根据模糊控制原理,设计磁悬浮模糊PID控制器。在Matlab/Simulink中建模,并分别对磁悬浮系统在两种控制器作用下进行仿真。对控制效果进行分析,证明模糊PID控制器对非线性系统控制具有良好的鲁棒性。
Magnetic Levitation System is a nonlinear and unsteady control system.The problem that the dynamic characteristics is usually not satisfactory when PID controller is applied to it.A fuzzy PID controller for control of magnetic levitation system is designed based on the principle of fuzzy control.The simulation model is built in the Matlab/Simulink,and do the simulation with PID controller and fuzzy PID controller separately.The analysis of control results shows that the fuzzy control is effective to the nonlinear control system.
