Linear ADRC for Speed Control of 5-Phase PMSM-based Electric Vehicles

Abstract

Linear active disturbance rejection control (LADRC) is proposed in this paper for the speed control of a five-phase Permanent Magnet Synchronous Motor (PMSM) propelling an electric vehicle (EV). LADRC presents a high ability for disturbance rejection beside high performance speed response and robustness. To improve the system's performance, LADRC estimate external perturbations and internal uncertainties as a total disturbance via an extended state observer (ESO). This observer allows real time compensation of estimated perturbations as state feedback to achieve the required performance. The proposed control strategy has been simulated using a MATLAB/SIMULINK platform under different operating condition to demonstrate its effectiveness.
