柴油机废气再循环系统控制器的设计研究

Design and Research about Exhaust Gas Recirculation Control Instrument for Turbocharged Diesel Engine

根据增压柴油机废气再循环(EGR)系统的要求,采用动态矩阵控制(DMC)算法设计EGR系统控制器。通过仿真系统试验证实了所设计的控制器可以应用于柴油机EGR系统,并能够使EGR系统有效降低柴油机氮氧化物(NOx)的排放。

According to the demand of exhaust gas recirculation (EGR) system on a turbocharged diesel engine, the method about dynamic matrix control (DMC) has been used to design EGR control instrument. The designed control instrument is proved actually by emulating experiment and makes EGR system reduce diesel nitrogen oxides (NO_x) emission efficiently.
