摘要
Many papers have been proposed speedsensorless vector control systems without encoders from the viewpoint of cost and environmental problems. We have proposed a simplified method of estimating the rotor position from the d-axis voltage and controlling the motor speed from the information of d-axis voltage too. In order to reveal the robustness of the proposed method, we have performed stability analysis and experiment when the stator resistances changed. To improve the stability of the system, stator resistance compensation is proposed. The simulation and experimental results are shown and discussed.
