This paper states a vector control system scheme of an induction motor drive with single-chip microcomputer.A set of simple vector control algorithm for the constant rotor flux is developed.The influence of the rotor resistance deviation on control charateristic is analyzed, and a new method of compensating for variation in rotor resistance is put forward.The experi- mental results verify that this method improves the performace of induction motor drive using a controlled current inverter effectively and can be used in industry.
