| 摘 要： | 本文为了解决传统PI控制器鲁棒性差、系统抗扰能力弱和动态响应的问题,针对永磁同步电动机矢量控制系统,设计了一阶滑模变结构速度环控制器。分析滑模转速控制器抖振产生的原因和影响,利用饱和函数设计了边界层滑模控制器,削弱了滑模控制器的抖振。搭建了在Matlab/Simulink环境下的仿真模型,并进行了仿真分析。仿真结果表明该控制策略减小了系统的超调与振荡,使系统具有较好的鲁棒性和动、静态性能。

| Abstract: | In order to solve the PI control problem associated with vector control of permanent magnet synchronous motor(PMSM),this paper studied on the speed regulator based on sliding mode control strategies.The causes and effects of elimination in sliding speed controller is analyzed,a novel design of boundary sliding mode controller with saturated function is proposed,which can chattering the elimination.Then establish simulation model in Matlab / Simulink environment and implement a simulation analysis based on t... |
