Feedback Linearization of Induction Motor Drives by using Fuzzy Logic Controller

Abstract

This paper represents a Direct Torque Controlled (DTC) Induction Motor (IM) drive that utilizes feedback linearization and Sliding-Mode Control (SMC). Another feedback linearization approach is proposed which is Fuzzy logic controller (FLC), which outputs a decoupled direct IM display with two state factors: torque and stator flux. This inherent linear model is utilized to actualize a DTC sort controller that preserves all DTC favorable circumstances and takes out its primary disadvantage, the flux and torque swell. Robust, quick, and swell free control is accomplished by utilizing FLC with corresponding control in the region of the sliding mode. Fuzzy logic controller guarantees robustness as in DTC, while the corresponding segment robustness out the torque and flux swell. The torque time reaction is like traditional DTC and the proposed arrangement is adaptable, profoundly tunable because of the P component. The controller design is displayed and its robustness solidness is analyzed in simulations. The FLC controller is contrasted and a direct DTC scheme with and without Feedback linearization. By using FLC controller extensive investigative comes about for dynamic response of a sensor less IM drive approve the proposed solution.
