摘要
文章研究永磁同步电动机(Permanent Magnet Synchronous Motor,PMSM)转速电流双闭环控制系统控制器参数的自整定方法。电流环根据辨识得到对象参数按照工程设计方法进行整定。速度环采用模糊自整定的方法。根据速度响应的超调量和调节时间,经模糊化、模糊推理和清晰化得到控制器参数调整量,从而改变速度控制器参数,直到满足指标要求,最后将参数固定。实验表明,该方法改善了速度响应性能,实现了永磁同步电机安装后伺服驱动控制器参数的快速自整定。
This paper researches on controller parameters self-tuning of the double closed loop control system of Permanent Magnet Synchronous Motor（PMSM）.The controller parameters of current loop are tuned by means of the engineering design method according to the parameters obtained by the identification of current loop＇s object.The controller parameters of speed loop are tuned by means of fuzzy self-tuning.According to overshoot and settling time of the speed response,the speed controller parameters are changed after getting the adjustment quantity by fuzzying,fuzzy reasoning and defuzzification and fixed until meeting the performance index.The experiment shows that this method improves the speed response and the controller parameters are tuned rapidly after the PMSM being fixed.
