| 摘 要： | 为避免对象连续模型和控制离散模型混合系统的复杂性,依据内燃机特有工作循环规律,以内燃机气缸内部气体守恒和传热规律为基础,建立了内燃机数学模型,以乙醇和汽油混合燃料内燃机为例,分析了模型的有效性,设计了数字PID控制器,仿真验证了控制器的控制效果。该模型可以在内燃机燃料供给数字控制算法设计和仿真分析中直接使用。

| Abstract: | In order to avoid the complexity of hybrid system combined with object continuous model and control discrete model,the mathematical model of internal combustion engine(ICE) was built according to ICE working cycle based on the principle of in-cylinder total energy conversion and the theory of heat transfer.For the ethanol-gasoline engine,the mode validity of model was analyzed,the digital PID controller was designed and the control effects were simulated.The model could be directly used in the digital contr... |
