Description
Summary:Accurate flux observation is critical to high performance torque control. In this paper, a new stator flux observer based on the model-optimized auto disturbance rejection control (ADRC) is proposed to improve the observing performance of direct torque control system at low speed. In terms of the frequency response function of stator flux, the sensitivity to machine parameters is analyzed according to the amplitude-frequency and phase-frequency characteristics. Simulation results show that better performance of the stator observer can be achieved under different speeds and load situations.
