Investigating Operating Modes and Converter Options of Dual Winding Permanent Magnet Synchronous Machines for Hybrid Electric Vehicles

Abstract-This paper proposes a model predictive speed control of a permanent magnet synchronous machine (PMSM). The control scheme has a cascade architecture, where the inner loop uses a finite set model predictive control scheme (FS-MPC) for the electrical subsystem, and the outer loop uses a dead-beat model predictive control for the mechanical subsystem. Due to the discrete nature of the control platform an accurate discrete model of the systems is necessary. In this work both systems, electrical and mechanical, are discretizated with a second order Taylor method. Simulation results are presented to validate the proposed control strategy.Index Terms-Model Predictive Control, variable speed drives, dead-beat control.

“…Permanent magnet synchronous machines (PMSM) are widely employed for applications such as servo control [1], [2], wind power [3], [4] and electric traction [5], [6], due to their high power density and efficiency. The most popular control methods for PMSM are the field oriented control [7] and direct-torque control [8].…”

“…In hybrid electric vehicles based on the independent motor and generator, there is a need for the bidirectional six-switch converter for each machine along with a DC-DC converter as an interface between battery and DC-link [16]- [18]. Various types of DC-DC converters, which are mostly appropriate options for EVs, have been investigated in previous research works [19]- [21]. In [19] an interface topology suitable for charging the batteries of an EV is reported.…”

“…A modified non-isolated single-inductor multiple-input buck DC-DC converter, which can be considered as an appropriate choice for hybrid dc sources based pure electric vehicle is addressed in [20]. For same application, a multi-input DC-DC interface, which is able to integrate three DC-sources such as photovoltaic (PV) system, fuel cell (FC), and energy storage system (ESS), is presented in [21]. Unlink the DC-DC conversion systems, which have experienced many improvements, DC-AC conversion parts of EV/HEVs have not been strongly explored in previous literature.…”

Due to the increased environmental pollution, hybrid vehicles have attracted enormous attention in today's society. The two most important factors in designing these vehicles are size and weight. For this purpose, some researchers have presented the use of the dual-mechanical-port machine (DMPM) in hybrid electric vehicles (HEVs). This paper presents two modified converter topologies with a reduced number of switching devices for use on DMPM-based HEVs, with the goal of reducing the overall size and weight of the system. Beside the design of the DMPM in the series-parallel HEV structure along with the energy management unit, the conventional back-to-back (BB) converter is replaced with nine-switch (NS) and five-leg (FL) converters. These converters have never been examined for the DMPM-based HEV, and therefore, the objective of this paper is to reveal the operational characteristics and power flow mechanism of this machine using the NS and FL converters. The simulation analysis is carried out using MATLAB/Simulink considering all HEV operational modes. In addition, two proposed and the conventional converters are compared in terms of losses, maximum achievable voltages, required dc-link voltages, the rating of the components, and torque ripple, and finally, a recommendation is made based on the obtained results. INDEX TERMS Back-to-back converter, dual mechanical port machine, five-leg converter, hybrid electric vehicle, nine-switch converter.

“…Multiphase motors, regardless of the type of machine, usually require a more extensive power supply system and more complex control algorithms [1][2][3][4]. Three-phase motors with independent, three-phase dual windings require two independent power supply circuits [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. As a result, two channels are obtained which, depending on the type of machine and the configuration of its windings, may be magnetically independent or partly independent.…”

This article presents the results of a comparative analysis of two electronically commutated brushless direct current machines intended for fault-tolerant drives. Two machines designed by the authors were compared: a 12/14 dual-channel brushless direct current motor (DCBLDCM) with permanent magnets and a 12/8 dual-channel switched reluctance motor (DCSRM). Information is provided here on the winding configuration, the parameters, and the power converters of both machines. We developed mathematical models of the DCBLDCM and DCSRM which accounted for the nonlinearity of their magnetization characteristics in dual-channel operation (DCO) and single-channel operation (SCO) modes. The static torque characteristics and flux characteristics of both machines were compared for operation in DCO and SCO modes. The waveforms of the current and the electromagnetic torque are presented for DCO and SCO operating conditions. For DCO mode, an analysis of the behavior of both machines under fault conditions (i.e., asymmetrical control, shorted coil, and open phase) was performed. The two designs were compared, and their strengths and weaknesses were indicated.
