Abstract

This paper presents a design and tuning method of the complex gain controller, based on the three-phase induction motormathematicalmodel complex transfer function to be used in induction motor control when the machine operates at low speed which is a problem so far. The complex gain controller was applied in the direct rotor field orientation controlmethod and also on the direct torque control method. It was designed and tuned using the frequency-response function of the closed loop system. The complex gain controller presents low complexity in the inductionmotor control implementation. Experimental results were carried out for the controller validation.
