Predictive Torque Control of Five-Phase Open-Ended Winding Induction Motor

The main intention of this paper is to compare conventional predictive torque control with the predictive torque control of stator open-ended winding five-phase induction motor drives (PTC-C and PTC-OEWFPIM) to be distinct in terms of the switching frequency reduction, torque and flux ripple, voltage stress, and common mode voltage minimization. In the proposed control technique, the dual two-level voltage source inverters enhance the output voltage levels from two to three. Both the inverters are connected on a common DC bus link, which allows undesired circulating common mode currents through the DC bus link, resulting in the rise of common mode voltage (CMV) would be mitigated with the proposed control technique. PTC-C and PTC-OEWFPIM controlled schemes are compared at a five-phase voltage space vector structure utilizing large voltage vectors only of individual inverters. The proposed PTC-OEWFPIM scheme was verified through MATLAB/Simulink simulations and compared with conventional PTC-C.
