MPGA-based-ECMS for energy optimization of a hybrid electric city bus with dual planetary gear

Abstract: To improve the fuel economy and reduce the exhaust emissions of a hybrid electric city bus (HECB) with dual planetary gear, a vehicle model is proposed based on the coupling mechanism between engine and battery motor in the gear. Then, two kinds of adaptive equivalent consumption minimization strategy (ECMS) algorithms based on fuzzy proportional-integral (PI) controller: Fuzzy PA-ECMS and Fuzzy MPGA-ECMS (MGPA: multiple population genetic algorithm), are established to improve the control effect of ECMS with … Show more

“…However, SGA only had one population per iteration for optimal individual selection, which was insufficient to assure loss and repeated selection. Through MPGA, the literature ( Yang et al, 2022 ) significantly enhances the algorithm’s speed. In addition, MPGA’s final iteration findings were consistent, indicating that MPGA’s target parameter search was more accurate and exhaustive.…”

“…After the objective function was constructed by Tikhonov ( Yang, 2016 ; Wang et al, 2019 ; Zhou et al, 20212021 ) regularization, MPGA ( Guo et al, 2020 ; Shi et al, 2021 ; Yang et al, 2022 ) was introduced to find the minimum value.…”

“…Besides, the gear ring (R1) of PG1 is connected to the planet carrier (C2) of PG2, and together they serve as the power output of the transmission. Ignoring the internal losses of the system, the coupling relationship of each component satisfies the following equation 35…”

“…In [28], authors proposed a ECMS strategy where the equivalence factor is adapted to driving condition of the bus by means of neurofuzzy inference techniques. Similarly, in [29], the equivalence factor of the ECMS in a HEV bus is adapted by means of genetic algorithms. A model predictive control based on Pontryagin's minimum principle is applied in [30] to a hybrid electric bus, with a fuel consumption that exceed the theoretical optimum of 6% according to simulation results.…”
