Generalized Predictive based Active Disturbance Rejection Control for Asymmetric Six-Phase PMSM Speed Regulation System

This paper proposes an active disturbance rejection predictive control (ADRPC) strategy to improve the robustness of the six-phase permanent magnet synchronous machine (PMSM) regulation system under complex working conditions. Compared to the traditional linear active disturbance rejection control (LADRC), ADRPC adopts the generalized predictive control (GPC) for the linear state error feedback control (LSEF) law to improve the control performance. Due to the continuous moving optimization based on the minimum variance control, this law improves the speed response compared to the conventional LSEF while maintaining stability. The system model and the controller mathematical derivation equation are established in this paper to build the simulation model. It is verified that ADRPC has better robustness than LADRC according to the comparison of simulation results.
