Abstract :
This paper deals with the identification method of rotor time constant in the 3-phase induction machines at standstill. The effect of inverter nonlinearity by dead time is alleviated by the proposed algorithm. The study proposes modified voltage model as reference model and uses current model as adaptive model. The algorithm is verified in the simulation and the experiment.
