摘要
以某型汽油发动机为改造对象,对汽油发动机电控系统进行了研究。设计了电控系统的总体结构方案,在Matlab/Simulink平台建立基于扭矩的发动机控制算法。在Simulink环境中,控制算法通过Moto Tron平台生成代码,编译到配套控制器中,验证控制算法是否达到预期要求,对基于扭矩控制算法的关键MAP进行了标定。最后采用自行设计的发动机电控系统在发动机台架上进行了整机的负荷特性试验,大大改善了发动机的动力性和燃油经济性。
Taking a gasoline engine as the transformation object, the electronic control system of gasoline engine is studied. The overall structure scheme of electric control system is designed, and a control algorithm based on torque of the engine is established in the MATLAB／Simulink platform. In the Simulink environment, control algorithm generated code by Mototron platform, compiled it into supporting controller to verify the control algorithm whether meeting the desired requirements; key map based on the torque control algorithm is calibrated. Finally, the self-designed engine control system is put into load characteristic machine test in engine stand, which greatly improves the dynamic performance and fuel economy of the engine.
