초록
In induction motor control systems driven by the indirect vector control scheme, the errorneous measurement of rotor speed results in incorrect flux angle estimate and consequently deteriorates the overall control performance. In this paper the effect of encoder fault on motor variables and control performance is analyzed by both theoretical approach and experimental study. A parity equation based on the power is suggested and applied to detect the incipient fault of encoder.
