Abstract :
The paper proposes a new nonlinear control strategy for three phase permanent magnet synchronous motor, in which the passivity-based controller is used as current inner loop and the active disturbance rejection controller is used as speed outer loop of the control system. Permanent magnet synchronous motor using above new control strategy has excellent dynamic response and steady-state performance in the high-speed and the low-speed operation. The simulation results show that the propose control strategy has good robustness to the disturbance of the power supply, stator resistance and inductance except for the above excellent performances.
