Multiphase permanent magnet synchronous motors (PMSMs) driven by the current source inverters (CSIs) are widely used in safety-critical applications, due to their fault-tolerant capability and high torque/power density. Nevertheless, the fault-tolerant field-oriented control method based on reduced order transformation matrices for addressing the adjacent double-phase open-circuit fault (ADP-OCF) in the CSI has not yet been established. Moreover, the influence of faulty phase winding currents has not been analyzed and suppressed. Hence, this article develops a fault-tolerant control approach that includes compensation for faulty phase winding currents in the case of ADP-OCF in the CSI. First, the optimized fault-tolerant winding currents are derived. Subsequently, the decoupled mathematical model and fault-tolerant space-vector-pulsewidth-modulation (PWM) strategy are established, and finally the fault-tolerant control is achieved. The effectiveness of the proposed fault-tolerant control scheme has been validated in the experimental results. Additionally, the utilization of compensating for faulty phase winding currents can lead to a further reduction in electromagnetic torque ripple by 19.32%.
