Fuzzy control of integrated current-controlled converter-inverter-fed cageinduction motor drive

This paper presents a performance analysis of a vector-controlled cage indu ction motor drive. The drive is fed from a current-controlled converter-inv erter system. The pulsewidth modulation current control technique is used t o derive the switching signals for the converter, as well as the inverter, Closed-loop control of the cage induction motor utilizes a fuzzy proportion al integral derivative speed controller. The advantages offered by the curr ent control converter-inverter link are exploited. In order to examine the dynamic performance of the drive system, its model is simulated and results are analyzed. The potential applications of this particular drive system a re outlined.
