This paper presents a novel model predictive current control (MPCC) with an optimum duty-cycle calculation scheme for asymmetrical six-phase permanent magnet synchronous machine (ASPMSM) drives. The proposed method takes advantages of the steady-state performance improvement and the weighting factor elimination. Both merits are owing to the optimum duty-cycle calculation scheme. On the one hand, for the α-β subspace, the optimal voltage vector set (VVS) is chosen from twelve ones and the corresponding optimal duty cycles are calculated using the proposed scheme. On the other hand, for the x-y subspace, the VVS can be determined according to that of α-β subspace and the optimal duty cycles are deduced using the same scheme. The voltage vector references in two subspaces are then obtained, and they are transformed to six-phase voltages for controlling the six-phase inverter. The proposed method is verified by experimental results based on a 2 kW ASPMSM prototype.INDEX TERMS Model predictive current control (MPCC), asymmetrical six-phase permanent magnet synchronous machine (ASPMSM), steady-state performance, weighting factor, duty-cycle calculation.

“…In this manner, the reliability and efficiency of multiple low-power supplies can be greatly improved. In another word, the multi-channel PMSM can be well replicated in other applications, such as microgrid distribution and aerospace propulsion, [5][6][7] because the number of working phases can be dynamically regulated according to the actual demand.…”

SummaryThis paper investigates an improved space vector pulse width modulation (SVPWM) and channel‐decoupled method for dual‐channel permanent magnet synchronous machine (PMSM) powered by unbalanced battery packs. Recently, individual power supplied voltage source inverter (VSI) is introduced considering insufficient power rating and unsafe driving in electrical vehicles (EVs). However, the issues of strong coupling and unbalanced power supplies exist between channels. Firstly, a modular topology is constructed to improve the reliability and security of the system. Secondly, the channel‐decoupled method is introduced based on multi‐dq rather than the conventional vector space decomposition (VSD) to eliminate coupling among multi‐channel. Thereafter, the variable distribution of voltage vectors (VVs) is corrected by the proposed SVPWM, where the switch can be operated appropriately. Finally, the comparative experiments are carried out focusing on decoupling and unbalanced power supplies, and the results present superior performance in terms of low torque fluctuation and balanced channel currents.

“…Faults taking place in traction machines and ensuring electric vehicle traction are also extensively studied in the literature. Mellor et al (2003), Tashakori and Ektesabi (2013), Kaplan et al (2021), Liu et al (2021), and Wu et al (2022) have proposed fault tolerant control strategies to handle possible faults in vehicle traction machine and ensure continuous and secure operation. Faults which may occur in the different sensors on vehicle boards are also extensively studied in the literature (Kommuri et al, 2016;Peñate et al, 2018;Yu et al, 2021;Zhang et al, 2021).…”

Secure power management strategy for direct torque controlled fuel cell/ supercapacitor electric vehicles

et al. 2022

View full text Add to dashboard Cite

High reliability is recommended in hybrid electric vehicle applications. In this study, a secure power management strategy has been developed for a fuel cell—supercapacitor hybrid electric vehicle. In addition to its ability to detect the occurrence of failures in vehicle power sources, the proposed power management strategy isolates the faulty source and reconfigures the control scheme to always guarantee bus voltage stability and vehicle traction even in faulty situations. The developed power management strategy enhances vehicle comfort and prevents exhausting one source over another by allowing the fuel cell and the supercapacitor to operate at different power levels. The multiloop control scheme associated with the power sources is highly reliable since both sources can run the vehicle alone and regulate the bus voltage. Vehicle speed and torque controllers are simultaneously tuned using a particle swarm optimization algorithm. Torque and speed ripples are automatically minimized via the use of a new proposed cost function. This approach made the controller design easier and gave the designer the possibility to tradeoff between the variables to be minimized.
