Comparative Study of Hysteresis Controller, Resonant Controller and Direct Torque Control of Five-Phase IM under Open-Phase Fault Operation

The need for regulating the operation of unhealthy motor drives has motivated researchers to modify control techniques in order be valid new drive state. use a fault-tolerant facility is an attractive feature multiphase machines; therefore, applicability different controllers been established under open-phase fault conditions. considered algorithms were utilized analyze system and evaluating capability regulate speed torque condition. However, majority these studies only one algorithm tested with faulty without comparing its performance other techniques. comparison vital way visualize features characteristics each algorithm. For this purpose, paper deals hysteresis controller, RFOC based on resonant controller direct (DTC) open-circuit A detailed between three presented outline main differences procedures identify most appropriate technique between.
