Abstract :
A novel stator flux and current estimator is proposed to estimate stator flux and remove dc offset error in induction motor with offsets of measured currents. The proposed stator flux estimator is able to solve the problem related with a pure integrator to estimate stator flux in induction motor for operating in a wide speed range and the proposed current estimator is able to remove offsets of measured currents. Normally a drift is made by integration of dc offset error present in the estimated stator flux due to DC offset in the measurement of phase current. The estimator can be able to solve a problem related the pulse with modulation (PWM) signal which is the signal is not sinusoidal signal.
