Research Of Fuel Cell Engine Control System And Information Fusion

In the recent years, with outstanding supply conflict of energy sources and more pollution from exhaust gas, research speed of fuel cell car is more and more fast. The research of Electric Vehicle is regarded as the background and it is with the Fuel Cell as the research object. It launches the research of the PEMFC engine control system, which is the high performance microprocessor as the core, adopting CAN fieldbus fibre communication, establishing reasonable control strategy and intelligent control arithmetic. A new kind of Fuel Cell Engine Control System will be developed.According to the performance which Fuel Cell Engine must reach, the architectural structure of the Fuel Cell Electric Vehicle is studied. Fuel Cell Engine hardware system of control system with the embedded microprocessor as the core is realized. The development and design of Fuel Cell Engine hardware platform, interface module and monitor module have been finished. At the same time Fuel Cell Engine control system should have certain anti-interface ability.The design of the software of the control system has been finished. Based on the DSP software research platform, used C language and assembler language programming, it is realized the design of the whole software. With the function of the software, it is divided four parts, which is initialization module, A/D sample module, control strategy module and communication module. Each of the model is independent mutually, which is convenience to programming and debugging.The design of some kinds of sensors and their circuits has been finished. According to the requirements which Fuel Cell Engine ask for to sensors, and taking surrounding of use into account, we choose some fit sensor and useful circuit for temperature testing and voltage testing and get good result.The algorithms research of Fuel Cell Engine have been launched. The paper analyses the advance of multisensor information fusion in fuel cell engine with lots of sensors, And design a model which can abide fault basing on neural network, the model has been used in temperature testing control system.The hardware design and software design of engine control system of Fuel Cell have been finished. Adopted the appropriate control strategy, an electric vehicle with fuel cell engine has succeeded to be assembled. After tested by practice, it has met the basic technical request of Dong Fong auto corporation and has formed the embryonic form of applied Fuel Cell Engine control system.
