| Abstract: | A new speed-sensorless control method based on reduced order observer was proposed which is used for speed identification in a direct torque controlled permanent magnet synchronous motor(PMSM) drive.The method combines reduced order movable observer of PMSM with model reference adaptive system(MRAS),and using the PMSM voltage function as the reference model,and the PMSM reduced order state function as the adjustable model.Theoretical analysis and simulation results showed that the PMSM sensorless control method for speed identification in a direct torque controlled system has stronger robustness and better dynamic and static performance. |
