Deadbeat Direct Torque Control for Interior Permanent Magnet Synchronous Motor Based on Active Flux Observer
摘要
Abstract
To improve the performance of permanent magnet synchronous motor drive system,a speed-sensorless deadbeat direct torque control (DB-DTC) of interior permanent magnet synchronous motor (IPMSM) was presented.Based on the discrete model of the motor,the deadbeat voltage control law of the torque and flux linkage was derived.By employing a graphical analysis method,the physical meanings of the voltage vector solution were explained clearly.The speed sensorless control of IPMSM was realized by combining the DB-DTC and the speed estimation method which based on the active flux observer.Simulation results verified the effectiveness of the proposed method.关键词
