Abstract This paper presents a closed-loop rotor flux observer based on the extended state observer (ESO) of active disturbance rejection control(ADRC) technology. The model can inhibit the influence of motor parameter perturbations and external disturbances without any parameter identification, so it has stronger robustness and fast response. Comparing with the speed estimation method of the model reference adaptive system (MRAS), a speed estimation adaptive law is derived through Lyapunov stability theory based on the proposed flux observer.

Key words： Active disturbance rejection parameter perturbations extended states rotor flux observer
