用于发动机控制模型的基于循环的平均值离散建模方法

Control-Oriented Engine Modeling with Cycle-Based Mean-Value Discrete Modeling Method

讨论了面向控制的发动机模型 ,并从角度域提出了基于循环的平均值离散建模方法。将其与目前主要用于实时仿真的模型进行对比 ,分析了这些模型与本文模型的不同特点。通过实例说明了在角度域上建立基于循环的平均值模型能够更好地反映发动机的离散本质。

In this paper,the control-oriented models are summarized.An event-based mean-value modeling method on the angle domain is put forward and is used to build a control-oriented mean-value model,which is compared to the popular models for real-time simulation.Through case study,it was verified that the discrete characteristics of the engine could be better reflected in the event-based mean-value model.
