Abstract :
In this paper, a fault detection technique by using parity equations applied to an induction motor is presented. The nonlinear model of A.C. motor is matched with the lineal model of D.C. motor in synchronous reference frame in order to generate a relative large change in the residual obtained with parity equations in presence of fault, which allows the simplicity and reliability of the fault detection. The good performance of the fault detection system is validated by using a simulator software of power electronics and motor control applications (PSIM).
