A Control Strategy Study On Exhaust Energy Recycling System Of Hybrid-electric Vehicle

of the by-pass valve is used to control the size of the exhaust back pressure. Thevariable geometry technology was used to control the turbine speed. Using fuzzy controltheory to control the exhaust gas by-pass valve opening and the turbine inlet guide vaneangle, the fuzzy controller was designed by using the MATLAB/Simulink, and thecorresponding fuzzy control rules are developed. In this paper, the high-speed generatorinverter control system is studied, using three-phase controlled rectifier to controlthree-phase alternating current rectifier, and the rectifier control system is studied andselect the capacitance in parallel filtering approach to filtering.4Exhaust gasenergyrecoverysystem simulationmodel was establishedinthispaper, including the turbine system model and high-speed generators recycling systemmodel. The recycling system control strategy simulation model was established,including the turbine control system model and the exhaust gas energy recovery invertercontrol system model, finally the simulation analysis of the whole system has carriedout. The results show that the hybrid electrical vehicle engine exhaust gas energyrecovery system control strategy can realize the recycling of waste gas energy.
