Abstract
- Smooth speed regulation is of importance for permanent magnet synchronous motor (PMSM) drives. However, the motor speed fluctuates aperiodically due to the internal disturbance (dead time of inverter and cogging torque) and external disturbance (sudden load torque changes). To address this problem, this paper proposed a proportional resonant (PR)-based active disturbance rejection control (ADRC) (PR-ADRC) for speed loop of PMSM drives. The PR regulator is combined with the linear extended state observer (LESO) to suppress the aperiodic speed fluctuation. Compared with the conventional linear ADRC, the dc disturbance rejection ability is retained, while the ac disturbance of system is compensated. Finally, the effectiveness of the proposed method is validated by the simulation results.
