摘要:
 针对在采用 PI 控制器的永磁同步电动机( permanent magnet synchronous motor,PMSM) 调速系统中,PI 控制器无法满足高精度控制要求,且易出现积分饱和的问题,提出一种基于快速幂次趋近律的滑模变结构控制器。该趋近律是在幂次趋近律的基础上,加入指数项以及系统状态变量。其中,指数项具有较快的收敛速度,可以解决幂次趋近律在远离滑模面时趋近速度慢的问题,系统状态变量可抑制由于引入指数项带来的抖振。基于该改进趋近律设计永磁同步电动机滑模速度调节器,并采用李雅普诺夫函数对其进行稳定性分析。经过与 PI 速度控制器进行仿真实验比较,结果表明采用该控制器的系统可实现速度无超调跟踪,并具有稳定性高、抗负载扰动强的优点。
Abstract:
In the speed control system of permanent magnet synchronous motor( PMSM) ,PI controller cannot meet the requirements of high precision control,which leads to integral saturation. The sliding mode controller based on a new fast power reaching law was proposed to solve these problems. This reaching law adds index term and system state variables to the traditional power reaching low. The index term has fast reaching speed which can improve reaching speed of power reaching low when system is far away from sliding surface. The system state variables has good effect in inhibiting the chattering problem caused by the index term. The sliding mode controller was designed based on this improved reaching law,and Lyapunov stability theory was used to analyze the stability of the system. The simulation and experiment is done compared with PI controller. The results show that the system with this designed controller can realize fast start-up without overshoot,and has the advantages of high stability and strong resistance to load disturbance.
