永磁同步电机调速系统变指数趋近律控制
Variable Exponent Reaching Law Control of Permanent Magnet Synchronous Motor Speed Control System
摘要
Abstract
In order to improve the performance of permanent magnet synchronous motor speed control system and enhance the robustness of speed regulation system,a reaching law based on variable exponent was proposed. Based on variable exponent reaching law,a sliding mode speed regulator for PMSM was designed and simulated. At the same time,comparing with the simulation results of conventional PI regulator and traditional exponential reaching law,it is found that the sliding mode control with variable exponent reaching law can effectively reduce torque ripple,and has good robustness for the static and dynamic characteristics of PMSM speed control system.关键词
