Abstract :
A model-reference adaptive control system (MRACS) approach is developed for identifying the parameters of an induction motor (IM) in PWM inverter-fed drives at standstill. The theoretical background of the approach is first presented. The case of known IM torque constant is then considered and an algorithm for identifying the IM parameters is derived. A sensitivity analysis to uncertainties in the torque constant is accomplished. Finally, the MRACS approach is applied to a commercial field-oriented IM drive and the motor parameters are identified. A test which validates the experimental results is also carried out
