摘要
研究了线性PI控制在PMSM调速系统中应用的不足,提出利用滑模变结构非线性控制弥补线性PI控制性能上的缺陷,将滑模控制的非线性控制特点与PI控制线性控制特点相结合,构成复合控制算法,提高速度控制的动态响应。在一台面装式PMSM样机上,设计了滑模PI复合控制算法,实现转速的闭环控制。通过仿真和实验,并与纯PI控制相比较,验证了所提控制算法的有效性。
The drawback of linear PI control in PMSM speed regulation system was studied and the idea of sliding variable structure （SVC） control was introduced into the speed regulation system of PMSM,combining nonlinear control characteristics of SVC with linear PI control to achieve composite control and to enhance system dynamic performance.The proposed composite control algorithm based on SVC was implemented in one surface-mounted PMSM and the closed loop of speed was also achieved.The effectiveness of the proposed composite control strategy was verified by simulation and experiment results,which were compared with the relevant results based on PI control only.
