this paper presents a design procedure for an adaptive power management control strategy based on a driving cycle recognition algorithm. the design goal of the control strategy is to minimize fuel consumption and engine-out nox, hc and co emissions on a set of diversified driving schedules. seven facility-specific drive cycles are considered to represent different driving scenarios. for each fa...

In this paper, a 20-ton prototype compound hybrid excavator is presented which includes assisting electric motor, swing electric motor, a super capacitor pack, an engine and negative flow hydraulic system. The energy-saving principle of hybrid excavator is introduced as well. The development rules of power train which include parameter design rules of key components and hierarchical structure o...

Based on dynamic model of electric power steering system(EPS), the application of mixed H2/H∞ control decides the values of the assisting torque to resolve ncertainty. Simulation results show that mixed H2/H∞ control is bette comparing with H∞ control to obtain low-frequency information from the road surface and inhibit high frequency interference, make the EPS system has better stability and t...

Plug-in Hybrid Electric Vehicles (PHEVs) offer a great opportunity to significantly reduce petroleum consumption. The fuel economy of PHEV is highly dependent on All-Electric-Range (AER) and control strategy. Previous studies have shown that in addition to parameters influencing Hybrid Electric Vehicles (HEVs), control strategies of PHEVs are also influenced by the trip distance. This additiona...

Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...

The renewable energy sources and plug-in electric vehicles (PEVs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. This paper presents modelling and control of a Building Integrated Fuel Cell and Plug-in Electric Vehicles (BIFC-PEV) in smart distribution systems. In BIFC-PEV system, conventional building elements could be replaced by sp...
