Abstract

Fault tolerance is gaining interest as a means to increase the reliability and availability of distributed energy system. In this project presents a new technique for fault detection in vector controlled induction motor (IM) drive. The proposed current estimation uses estimation uses d- and q-axes currents and is independent of the switching states of the three-leg inverter. While the technique introduces a new concept of vector rotation to generate potential estimates of the currents, speed is estimated by one of the available model reference adaptive system (MRAS) based formulations. The objective of the controller was to control the current that supply into the induction motor. The proposed method is extensively simulated in simulated in MATLAB/SIMULINK.
