摘要
分析了混合动力汽车多能源动力总成控制系统对汽油机节气门的响应要求及电子节气门系统的研发现状,提出了基于模糊逻辑的电子节气门PWM控制算法,并以英飞凌TLE6209R芯片为核心设计了电子节气门的电路硬件部分。在此基础上,建立了电子节气门直流电机控制系统的仿真模型。采用dSPACE快速控制原型系统,完成了被控电子节气门不同工况下的实时仿真。仿真结果验证了控制算法及控制系统的有效性,为产品级的电子节气门控制器的开发提供依据。
The response request for the gasoline engine throttle system of the hybrid electric vehicle power control unit and the status of electronic throttle system R&D are analyzed. The PWM control algorithm for electronic throttle system based on fuzzy logic is put forward, and the circuit taking the Infineon TLE6209R chip as the core has been designed. Based on the algorithm and the circuit, the simulation model has been set up by Matlab/Simulink. The rapid control prototyping system with dSPACE is adopted to operate the real-time simulation on different mode, and the simulation result shows that the control algorithm and circuit are all effective. It would be beneficial to develop the product-throttle controller.
