Research on Permanent Magnet Synchronous Motor Sensorless System Based on Improved Active Disturbance Rejection Control
摘要
Abstract
Research on the speed identification of permanent magnet synchronous motor (PMSM) vector control speed sensor less system.Designed speed-loop controller and current-loop controller based on active disturbance rejection control (ADRC) instead of the PI regulator.The speed was accurate estimated by extend state observer's (ESO) accurate estimation of disturbance,then the sensor less speed control had been realized.The typical active disturbance rejection controller was improved,the structure of ADRC controller was simplified and fuzzy control algorithm was introduced to optimize the parameters of the controller.The simulation results showed that compared with PI regulation,the ADRC regulation could meet the requirements of the high performance control of PMSM system;compared with the model reference adaptive system (MRAS),when the motor at low speed,the speed estimation effect was better based on the ESO observation,it was not sensitive to the variation of motor parameters and the robustness was stronger.关键词
