N2 - A dual motors system, driven by a five-leg voltage source inverter (FLVSI), is considered as a feasible option for low-cost and fault tolerance applications. This article analyzes the effect of angle regulation for a FLVSI driving dual motors combined with an improved predictive control scheme. Firstly, a deadbeat-based model predictive control (DB-MPC) scheme is proposed to realize duty cycle allocation for FLVSI. It coordinates the conflicting switching-states demands of common leg from dual motors and improves the voltage utilization of whole system. Moreover, a broad discussion of angle controller is conducted, which can be employed to regulate the phase angle difference between two motors for minimizing the common leg current or expanding speed range depending on the different control aims. Finally, a simulation model is established to verify the effectiveness of the proposed control strategy. The test results indicate that the proposed DB-MPC scheme has higher output capacity and yields smaller current ripple. The regulation of phase angle can minimize the common leg current or expend the speed range effectively.
