摘　　要：采用基于模型的设计方法,以扭矩协调作为核心控制策略,利用Matlab/Simulink工具搭建GDI汽油机控制策略算法模型。运用RTW自动代码生成技术将模型转化为可执行代码,并下载到MotoTron快速原型中,进而搭建了一套基于扭矩协调的GDI汽油机控制系统。在发动机台架上对该控制系统进行测试表明,其在起动、怠速以及低负荷工况下均可以对GDI汽油机进行稳定控制,功能满足开发目标。In this paper, we introduce the model-based design approach and build a GDI engine control algorithm model with torque coordination as the core control algorithm. Then the model is transformed to executable code by using RTW automatic code generation technology, and is downloaded to rapid prototyping. Finally we build a GDI engine control system based on the torque coordination. Then we test and validate the system by engine bench. The results show that the system can perform stability control on the GDI engine at conditions of starting, idling and low load driving, with functions complying with the development objectives.
