Dual Permanent Magnet Synchronous Motors Fed by a Five-Leg Inverter System Using Maximun Torque per Ampere

Abstract:

In this paper, a maximum torque per ampere (MTPA) control strategy based on space vector pulse width modulation (SVPWM) is adopted in a dual three-phase interior permanent magnet synchronous motors (PMSMs) system with a five-leg inverter. The simulation model is established in Matlab/Simulink based on the mathematics model of PMSM and the current control method. And the simulation results of the proposed current control strategy are compared with those of i_d=0 method in order to verify the performances and characteristics of MTPA control stategy.
