| 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,提出了一种新型指数趋近律,与常规指数趋近律不同,该趋近律将趋近速度与系统状态量的变化相关联,克服了常规指数趋近律的缺点,有效抑制了滑模的固有抖振问题,并增大了趋近速度.将该趋近律应用于永磁同步电动机调速系统,设计了基于新型指数趋近律的滑模变结构速度控制器,以取代传统PI 调节器.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.

| Abstract: | To improve dynamic quality of permanent magnet synchronous motor(PMSM) speed servo system,a novel exponent reaching law was proposed.Different from the conventional exponential reaching law,the reaching speed of novel reaching law was associated with the changes of the system state;the novel exponential reaching law can overcome the disadvantage of traditional reaching law,suppress the chattering and improve the reaching speed.The novel reaching law was applied to the PMSM speed servo system;a novel speed c... |
