In the traditional adaptive full-order observer (AFO) for speed-sensorless induction motor drives, the estimated rotor flux error is neglected in the speed estimation algorithm. In this paper, the estimated rotor flux error and an error coefficient are adopted in the speed estimation algorithm to improve the robustness of speed estimation. Based on the… CONTINUE READING
