Abstract
The indirect vector control scheme is machine parameter dependent. And parameter identification schemes are themselves dependent on some motor parameters. This paper analyzes parameter sensitivities of two identification methods, reactive power model and q-axis flux model based on MRAS are analyzed through extensive simulations and experiments on an induction motor. Then a novel scheme is proposed based on hybrid model by combining the two adaptive models. The results demonstrate that the hybrid scheme is almost parameter independent in different operation conditions. And it is considered useful in practical application.
