摘　　要：为了提高永磁同步电动机(permanent magnet synchronous motor,PMSM)调速系统的动态品质,提出了一种新型趋近律,在纯指数趋近率基础上,引入终端吸引子与系统状态变量的幂函数,对滑模控制抖振进行了抑制,并提高了滑模趋近速度;基于该趋近律对永磁同步电动机滑模速度调节器进行了设计,与PI调节器、常规指数趋近律分别进行了试验比较,仿真和实验结果表明,该速度控制器能够有效地提高系统的静态、动态特性与鲁棒性。To improve dynamic quality of permanent magnet synchronous motor （PMSM） speed servo system, a novel reaching law was proposed, different from the conventional reaching law, switching function was not included in the novel reaching law, and the terminal attractor and the system state were used to suppress the chattering and improve the reaching speed. The novel reaching law was applied to the PMSM speed servo system; a novel sliding mode speed controller was designed to replace the traditional PI regulator. Simulation and experimental results show that the novel speed controller can improve steady, dynamic performances and robustness characteristics of speed servo system obviously.
