CONCLUSIONS This paper present improved PLL for encoderless control using sliding mode compensator in state based observer. The proposed method does not depend strongly on observer parameter. It is verified by simulation

11、 as well as from experiment that the proposed method is robust against the load inertia variation when compared to state based observer. As a result, the proposed method gives better rotor position estimation with increase plant stability, thereby confirming the effectiveness and validity of the pro
