PMSM Vector Control Based on Improved ADRC

This paper research a vector control strategy of PMSM based on ADRC technology. That is, using the vector control method, an ADRC is designed for the speed control loop of the PMSM to replace the PI controller. At the same time, in order to facilitate the parameter adjustment of the ADRC, some improvements are made to the typical structure of the ADRC, and the simplified ADRC is applied to the PMSM vector control system. To improve the PMSM speed control performance. Simulation results show that the above control strategy is feasible.
