A simple vector control technique for 3-phase induction motor under open-phase fault based on GA for tuning of speed PI controller

This paper discusses a simple vector control technique for vector control of faulty 3-phase Induction Motor (3-phase IM under open-phase fault) based on Rotor Flux-Oriented Control (RFOC). It is shown in the adapted system for vector control of the faulty IM, it is essential for the speed PI controller coefficients to modify. For this reason, Genetic Algorithm (GA) is employed for tuning of speed PI controller. The results of this study show that the proposed drive system have acceptable good speed and torque responses.
