Multiphase machines have a higher efficiency, greater fault tolerance, lower torque ripple and reduced rated power electronics rating compared to their three-phase counterparts. However, the drive system and control is more complicated for the multiphase machines. A novel drive system for a split-phase permanent magnet motor and dual inverters is presented and explained in this paper. Field-oriented control (FOC) is utilized for the speed controlwhich a new decoupled current controllers are exploited to remove the tight coupling between the d and q current components. An eigenvalue decomposition method is used to transform the system state-space equations to its modal form. Based upon, the decoupled PI current controllers are proposed including the design procedure. A maximum torque per ampere (MTPA) strategy is developed to determine the reference values for the current controllers. Simulation results are provided to show that the proposed drive system has a good dynamic and steady state performance in a speed control system.
