基于模型的燃油动态补偿器的仿真研究

Simulating Research of Fuel Dynamic Compensator

针对电喷汽油机列出了线性模型和最常使用的均值模型对进气管空气和燃油动态过程的描述 ,以及基于这些模型的理想燃油补偿器的数学表达式。同时 ,通过在matlab中的仿真 ,分析了瞬态时线性补偿器的误差及其产生的原因。

With regard to electronic control injection gasoline engines, this paper represents the linear models and the mean value models for air mass and fuel mass dynamics in intake manifold, as well as the mathematical expressions of compensators based on these models. Simultaneously, the defects of linear compensator and its causes are analyzed by the MATLAB under instantaneous conditions.
