Abstract :
A novel approach to Permanent Magnet Synchronous Motor(PMSM)Drive System and Stator Flux Observer based on line active disturbance rejection controller (LADRC) is presented in this paper. The LADRC controller does not dependent on the accurate mathematical model of motor. which lead to good dynamic and static performance for drive system. A flux observer based on line extended state observer (LESO) is also designed in this paper to provide a direct estimate of the torque. Simulation and experimental result show a good dynamic and static performance of PMSM drive system is achieved.
