Abstract

Pole-phase modulation-based induction motor (PPMIM) drives possess the capability of providing an extended range of speed-torque for high-power traction application with the available additional degrees of freedom in the multiphase machine. As observed in previous open-loop results of PPMIM drives presented in the literature, the transient currents often exceed twice the rated currents. To address this issue, this article focuses on the modeling and advanced control of the PPMIM drives during all possible pole-phase combinations. The dynamic mathematical modeling of the PPMIM in actual phase variable domain is presented in detail. Since this model involves time-dependent inductances and torque, the machine model equations are transformed into the dq domain using transformation matrices. The transformation matrices, modeling equations in the arbitrary reference frame, and MIM are modeled by considering all parameters of possible pole-phase combinations. Based on the proposed modeling equations, an indirect field-oriented control (IFOC) is implemented for PPMIM drives for smoother operation in all possible modes of operation. The modeling equations, as well as IFOC of PPMIM drive, are implemented in MATLAB to illustrate the behavior of machine during transients as well as different load torques. The proposed concepts are also validated on laboratory setup, and the hardware results are demonstrating the smoother transition as well as steady-state operation of PPMIM drive in pole changeovers as well as both pole-phase combinations. © 2013 IEEE.
