摘　　要：磁浮列车运行控制是一个复杂的非线性控制系统,基于传统PID算法的速度控制器不能消除时变干扰影响,动态性能差。文章提出基于Fuzzy-PID控制的磁悬浮列车速度闭环跟踪控制算法,利用模糊逻辑在线计算PID参数修正量。数据仿真试验结果表明,Fuzzy-PID控制可以明显改善速度闭环控制器的响应特性,提高列车运行控制系统的动态性能。Maglev train operation control is a complex nonlinear control system.the speed controller based on traditional PID algorithm cannot eliminate the influence of time-varying interference and has poor dynamic performance.In this paper,a closed-loop tracking control algorithm for maglev train speed based on Fuzzy-PID control is proposed,and the PID parameter correction is calculated online by fuzzy logic.The results of data simulation test show that Fuzzy-PID control can obviously improve the response characteristics of the speed closed-loop controller and improve the dynamic performance of the train operation control system.
