Advanced Control Method of 5-Phase Dual Concentrated Winding PMSM for Inverter Integrated In-Wheel Motor

Abstract

This paper presents some techniques for driving novel 5 phase dual winding PMSM (Permanent Magnet Synchronous Motor) for the in-wheel motor. The motor realizes winding change over characteristics that can expand driving area from high-torque mode to high-speed mode due to the dual winding construction. However, the dual winding structure makes a high-current ripple due to high coupling between windings. The paper proposes some control methods to reduce the current ripple, including inverter career ripple. The paper also presents harmonics current injection, such as the 3rd harmonics current injection method, to reduce the torque ripple and generate higher torque.

Design and Experimental Evaluation of an In-Wheel Flux-Switching Machine for Light Vehicle Application

“…The use of high energy magnet and flexible design for both rotor and stator structures offers a high power and torque density solution with the possibility of tailoring the design according to the application requirements. Examples of current improvements include the study of different PM arrangements to enhance output torque [29][30][31] or different stator winding arrangements to extend speed range operation [32,33].…”

Vector control of permanent magnet synchronous motor drive system based on new sliding mode control

“…Therefore, upgrading and transforming some control systems is urgent [6][7][8][9][10][11]. In recent years, modern control theories such as fuzzy control, model predictive control, auto disturbance rejection control (ADRC), sliding mode control (SMC), and others have been applied to PMSM control [12][13][14][15]. Sliding mode control, in particular, is gradually being adopted in permanent magnet synchronous motor control due to its simple design, control algorithm, and insensitivity to a parameter and external disturbance changes.…”
