Research on Permanent Magnet Synchronous Motor Direct Torque Control Sensorless System Based on Improved Active Disturbance Rejection
摘要
Abstract
To solve ripples on stator flux linkage when using traditional voltage model to estimate at low speed in the direct torque control (DTC) of permanent magnet synchronous motor (PMSM) system.The stator flux and rotor speed were estimated by the extended state observer (ESO) of the active disturbance rejection control (ADRC) technique,and the sensorless speed control had been realized.The structure of the ADRC controller was simplified and fuzzy control was introduced to optimize the parameters of the controller.In the DTC system,the improved ADRC regulator was used to replace the PI regulator for speed regulation,and the anti-interference ability of the system was improved.The space vector pulse width modulation (SVPWM) instead of the traditional selecting table and hysteresis comparator,the switching frequency constant and the ripples on flux linkage and torque had been reduced.Simulation results verified the effectiveness of this algorithm.关键词
