摘要
针对轴向磁通永磁弧形电机在低转速下抗干扰能力弱、动态响应能力差的问题,采用滑模速度控制器代替传统PI速度控制器。首先建立轴向磁通永磁弧形电机的数学模型,然后搭建滑模速度控制器仿真模型,最后在Matlab/Simulink中对整个矢量控制系统进行仿真分析。结果表明,滑模速度控制器比传统PI速度控制器响应能力更快、抗干扰能力更强。
This paper addresses the limitations of low-speed anti-interference and dynamic response ability in arc-linear axial flux permanent-magnet synchronous machines.To improve these characteristics,the traditional PI speed controller is replaced with a sliding mode speed controller.The mathematical model of the machine is established,followed by the simulation model of the sliding mode controller.The entire vector control system is then analyzed using Matlab/Simulink.The results demonstrate that the sliding mode speed controller has improved response speed and anti-interference ability compared to the traditional PI speed controller.
