改进型滑模变结构电机控制的脉振电流注入法研究
Research on Pulse Current Injection Method Based on Improved Sliding Variable Structure Mode Motor Control
摘要
Abstract
In order to improve the control performance of position sensorless technology of permanent magnet synchronous motor (PMSM),a sliding variable structure controller mode was used to replace the traditional PI controller,and a new approach law was presented to improve the output of the sliding mode controller model,which had weakened the chattering of the traditional sliding mode control and improved the anti-interference ability of the control system.In the analysis of position sensorless technology,a high-frequency pulse current signal injected in two-phase stationary coordinate system was characterized by a high signal to noise ratio owing to the introduction of a high-pass resonant filter.The simulation results showed that the application of the sliding mode variable structure controller in the high frequency pulse current injection method with high-pass resonant filtering improved the accuracy of the rotor position estimation and enhanced the robustness of the control system.关键词
