Parallel Hybrid Electric Vehicle Fuzzy Control Simulation And Design Optimization Strategy

A hybrid electric vehicle has two sets of power systems, the controllingstrategy between two sets of power systems is the core. This article sets thehybrid electric vehicle as the research background, puts forward the fuzzycontrolling strategy of Parallel hybrid electric vehicle, and builds the models ofthe main components of hybrid electric vehicle in Matlab. On the basis oforiginal traditional vehicle model, this article increases the fuzzy controllermodel, and then imports the models into the professional tool softwareADVISOR (FREE). By setting the simulation parameters, the engine workingpoint distribution and motor working point distribution are be showed. In thispaper, the main works are follows:Firstly, the advantages and disadvantages of the structure of parallel hybridelectric vehicle are be compared, and then set the stage for the following;Secondly, the vehicle engine, motor and battery parameters of calculation ofparallel hybrid electric car are be determined; Again, the use of Matlab tools forparallel hybrid electric vehicle modeling of several big models. The idea offuzzy logic controlling strategy is putted forward, the fuzzy controller is appliedin vehicle model, design a fuzzy controller, and the second development isdesigned in ADVISOR; Finally, in view of the establishment of membership,this paper has optimized by algorithm.Through comparing the simulation results, this paper draws the conclusion:the SOC of parallel hybrid electric vehicle adopted fuzzy control strategy isrelatively smooth, and the engine works at the higher efficiencies.
