本文简单回顾和展望了控制理论在发动机自动控制系统尤其是空燃比及怠速控制中应用的现状和未来,空燃比控制系统自从应用到商用汽车发动机上以来,这个系统的基本控制框架一直没有改变,只是在动态空燃比控制中有些变化,采用了新的模型,并由此产生较好的控制结果,应用反馈控制理论的最有代表性的例子是怠速控制,它是发动机控制系统中少有的几个闭环控制中的一个,分形控制理论具有很大的潜能,如果被应用于这些控制系统之中,有可能产生卓越的控制效果。
This paper simply reviews and foresees the status quo and future of the application of control theory in engine automatic control system, especially in air-fuel ratio and idle speed control. Since the application of air-fuel ratio control system to commercial vehicle engine, the basic control framework of this system has not changed, Only some changes in the dynamic air-fuel ratio control, the use of a new model, and thus produce better control results, the most representative example of the application of feedback control theory is idle control, which is rare in the engine control system One of several closed-loop control, fractal control theory has great potential, if applied to these control systems, it is possible to produce excellent control.
