An Effective Predictive Torque Control Strategy for Five-Phase Induction Motors Under Normal and Fault Condition

Abstract

Stand-alone electric propulsion systems require high fault tolerance, and multiphase induction motor drives offer significant advantages over their three-phase counterparts in this regard. These drives can maintain functionality under fault conditions, ensuring reliable post-failure operation. This paper presents a predictive torque control technique applied to a five-phase induction motor. The proposed approach introduces a notable feature: the use of two distinct cost functions for torque and flux. This dual-function strategy simplifies the control process and enables a rapid dynamic response. The proposed technique's performance is evaluated against classical field-oriented control and direct torque control under both normal and open-phase fault conditions. Simulation results demonstrate the method's effectiveness in accurately tracking flux and speed references. Moreover, the proposed strategy significantly reduces flux and electromagnetic torque ripples, both during normal operation and post-fault.
