On the sensorless rotor position control of the permanent magnet synchronous motor: An active disturbance rejection approach

摘要

This paper presents a rotor position sensorless control for the permanent magnet synchronous motor (PMSM), based on an active disturbance rejection control technique and an integral reconstructor for the rotor position estimation. The control law uses a generalized proportional integral observer (GPIO) for estimating and compensating the unknown uncertainties which the PMSM system is subject. The control law is designed in the a-p coordinate as it is just like the integral reconstructor of the PMSM rotor position. The validity and robustness of the proposed scheme is verified via realistic co-simulations using Matlab/Simulink and PSIM packages.
