Direct Torque and Flux Control of Five-Phase Induction Motor Using Fuzzy Logic

In this paper a fuzzy logic scheme is applied for direct torque fuzzy control (DTFC) of five phase induction machine (FPIM). The proposed DTFC based on fuzzy logic technique switching table is described and compared with conventional direct torque control (DTC). The proposed fuzzy control strategy is simulated using Matlab/Simulink software. The simulation results show that DTFC method reduces torque ripple and stator flux variation and improves dynamic response. High Phase Order (HPO) multiphase motor a type of AC motor that has been developed in the last decade and due to its advantage over the three phase motor, many scientists and researchers focus on it. Each electrical motor that have over three phase stator winding can be in HPO class. Researcher demonstrated that HPO drive motor many advantage over conventional three phase motor drives. Multiphase Motor drives are mostly proposed for high power application such as traction and hybrid vehicles aircraft and etc. The advantage of multiphase machines, with respect to conventional three-phase machines are reduced torque pulsations, reduced dc-link harmonics, higher torque density, greater fault tolerant, improvement of the drive noise characteristic, reduction in the required rating per inverter leg and achieving a high power motor
