Fault-Tolerant Control of Five-Phase Induction Motor Under Single-Phase Open

This paper deals with fault-tolerant control of five-phase induction motor (IM) drivesunder single-phase open. By exploiting a decoupled model for five-phase IM under fault, the indirectfield-oriented control ensures that electromagnetic torque oscillations are reduced by particularmagnitude ratio currents. The control techniques are developed by the third harmonic current injection,in order to improve electromagnetic torque density. Furthermore, Proportional Resonant (PR) regulatoris adopted to realize excellent current tracking performance in the phase frame, compared withProportional Integral (PI) and hysteresis regulators. The analysis and experimental results confirm thevalidity of fault-tolerant control under single-phase open. KCI Citation Count: 7
