Sensorless Active Disturbance Rejection Control of PMSM Based on Extended Kalman Filter

This paper introduces a sensorless Kalman filter for current loop control using Adaptive Active Disturbance Rejection Control (ADRC). In ADRC, the Extended State Observer is optimized through an adaptive resonance controller, allowing it to estimate uncertain periodic and aperiodic disturbances. ADRC has the advantages of not relying on system models and strong disturbance rejection capabilities. Compared to traditional PI control, this method provides faster dynamic response. Combined with the speed and rotor position estimated by the Kalman filter, sensorless control of the permanent magnet motor is implemented. Finally, the effectiveness of the proposed control algorithm is validated on a simulation platform.
