摘要：为了改善永磁同步电机(PMSM)调速系统的动态品质,提出了一种基于变速趋近律方法的PMSM滑模速度控制策略。为了提高传统指数趋近律的收敛速度和消除系统抖阵现象的影响,在传统指数趋近律的基础上提出了一种新型变速趋近律方法,并应用该方法设计了一种PMSM调速系统的滑模速度控制器。通过仿真和试验结果对比分析,证明该算法不仅改善了系统的鲁棒性能,同时改善了系统的动态响应速度。
In order to improve the control performance of permanent magnet synchronous motor （PMSM） drive system, a siding mode speed control strategy based on an improved reaching law method was proposed. To shorten the reaching time and weaken system chattering of the conventional exponential reaching law, a novel reaching law based on traditional reaching law was proposed, and the method was applied to PMSM drive system. Compared with traditional PI controller, simulation and experiment results showed that the proposed controller improve the system robustness and dynamic performance.
