The lack of a load power prediction function in conventional multi-wheel electric drive vehicles leads to lags in control action. To address this issue, we developed a real-time energy management strategy with improved load power prediction accuracy. Based on an assessment of the overall vehicle structure, a mathematical model for each power source was established using theoretical analysis and data fitting. A method for the joint prediction of non-stationary load power combining Kalman filter and Markov chain forecasting methods was established, and a multi-objective optimization function was constructed under the nonlinear model predictive control framework. To enable real-time optimal control command, a sequential quadratic programming method in the finite time domain was applied. Finally, the multi-power source was optimized and coordinated. Multi-road driving experiments were carried out using a hardware-in-the-loop simulation platform. Comparisons of energy management control strategies with and without power prediction revealed that applying the former enhances the predictability of future load power, significantly optimizes the coordinated control of multiple power sources, improves vehicle fuel economy, and stabilizes bus voltage and battery state of charge. Moreover, it has specific reference significance in engineering application scenarios under conventional model predictive control.INDEX TERMS energy management strategy, integrated power system, load power prediction, model predictive control, multi-wheel electric drive vehicle

“…Hybrid electric vehicles (HEV) are a good candidate in the transport sector owing to better fuel economy and reduced greenhouse gas emissions [1,2]. In conventional HEVs, the main power comes from two major sources of motion: the internal combustion engine (ICE) and electric motor which may be required to run accessory loads such as power steering, water pump, air conditioner, heating system, power windows, and lights, irrespective of the vehicle movement [3]. This power needs to be available on demand, which can be fulfilled by using either a drive-bywire system or electric accessory drive (EAD) system in HEV.…”

“…This power needs to be available on demand, which can be fulfilled by using either a drive-bywire system or electric accessory drive (EAD) system in HEV. In the drive-by-wire technique, several electric motors of different power ratings, various inverters and their gate drive circuits, and a Lundell alternator are used to drive these accessory loads [3,4]. This makes the system inefficient and increases the cost, and overall weight.…”

“…In the EAD system, one motor and one generator convert energy into mechanical and electrical power separately, which requires more space for two separate machines [5]. However, it is possible to convert the input energy into mechanical and electrical power independently, using a single machine in the EAD system [1,3,4] making it more compact. For these EAD systems, the researchers have adapted different configurations of electrical machines.…”

Three-Phase Dual-Winding Multitasked PMSM Machine Using Double Layer Concentrated Winding for HEV Application

This paper proposes a three-phase dual-winding permanent magnet synchronous machine (PMSM) providing multitasked operation for accessory drive systems in hybrid electric vehicles (HEV). The novelty of this research lies in the machine having special slots and pole combinations with specific configuration of two sets of double-layer concentrated group winding separated by the unwound tooth between the phase groups formed on the same stator to achieve both the motoring and generator operation simultaneously as well as independently. These operations are accomplished by incorporating motor and generator winding separately on the same stator of a single PMSM machine. This single machine is particularly designed to eliminate the mutual coupling between these two sets of windings such that the load variation on the generator does not affect the mechanical output power of the motor. To confirm this multitasking, the electromagnetic design of the machine has been presented, and its operating modes are analyzed. The performance is compared using finite element analysis with that of a conventional PMSM machine having a double-layer winding configuration.INDEX TERMS Accessory drive system, double-layer concentrated winding, dual-winding machine, hybrid electric vehicles, permanent magnet synchronous machine.

“…For example, electric aircraft and micro-grid systems prioritize reliability in addition to high efficiency and compactness [3]. Furthermore, some applications focus on operating individual machines in different modes [8], [9]. In these modes, the machine may operate as a motor and generator, either simultaneously or independently.…”

In this study, a dual-port wind-energy conversion system has been proposed. A double-fed permanentmagnet synchronous generator (DFPMSG) forms the central part of the system, where the concentrated single-layer winding configuration of the generator enables electric and magnetic isolation between the ports. DFPMSG has two three-phase terminals out of the stator; one is connected directly to the grid, whereas the other is tied to the grid through a back-to-back converter. This study investigates design issues caused by the DFPMSG port with a direct grid connection. The unique design issues of the proposed system include determining the slot/pole combination using wind data and determining the minimum reactive power requirement for the port with a direct grid connection. Next, the load-sharing capability among the ports of the proposed system is presented through a detailed investigation of three schemes. Experimental work is presented for a 5-kW prototype DFPMSG system to illustrate the isolation among the ports, minimized reactive power demand on the port with direct grid connection, and load-sharing ability among the ports for different control schemes.INDEX TERMS Double-fed machines, electric machine design, multi-port systems, permanent magnet synchronous generators, wind energy.
