Abstract Due to characteristic of dual-inverter power supplying and existence of zero sequence loop, the open wingding permanent magnet synchronous machine (OW-PMSM) system with common DC bus has certain fault tolerance ability. And the influence of zero sequence current should be considered because of the zero sequence loop. However, when open phase fault occurs, the original mathematical model is no longer applicable. Thus, the torque ripple will become larger and the control performance will worse if the control strategy before fault occurrence is adopted. In this paper, according to the characteristics of OW-PMSM, the coordinate transformation was redesigned and a new mathematical model in dq-axis was obtained. The new torque equation has concise form which makes the torque control more convenient. At meantime, the dq-axis voltage equation is decoupled based on new coordinate transformation so that the calculation burden is reduced and control performance is improved. In order to further improve the current control performance, three vector based model predictive control (MPC) strategy was adopted. Then the voltage vector plane after open phase fault is reconstructed and the duty cycle can be calculated according to the new basic voltage vectors. The experimental results verify the effectiveness and superiority of the proposed method.
