Speed Identification for Vector Control of Induction Mortor

A model-reference adaptive system (MRAS) for the Identification of induction motor speed is proposed in the paper. According to a transformed form of a mathematical model of induction motor, a model-reference adaptive speed indentification algorithm is obtained by using easily-measured motor stator voltage and current. The algorithm is simple, and it have a higher accuracy, it provides a prerequisite for the implementation using a low coat single-chip microprocessor.
