Abstract
In this paper, the vector control of a parallel-connected two five-phase permanent magnet synchronous machines (PMSMs) drive supplied by a single current-controlled voltage source inverter is presented. This system consists of a two five-phase PMSMs; the stators windings of both machines are connected in parallel in appropriate manner by using of the phase transposition property, which allows a decoupled control of the two machines. Based on the mathematical model of the multi-machine drive system, the decoupled dynamic of each machine from the group is obtained using the vector control algorithm. The independent control is ensured by controlling the stator currents and the speed of each machine under vector control consideration. Selected simulation results are presented to validate the effectiveness of the proposed control method under various dynamic operating conditions.
