The development of a clean and fuel efficient diesel engine control method is required for enhancing global environmental protection. However, in the EGR control of turbo-charged engines, the system has nonlinear characteristics, and there is mutual interference on the engine performance between the EGR valve and the VNT guide vane inputs. In this paper, we propose a cooperative control method to deal with the nonlinearity of the diesel engine, in which a method for model identification and MPC (Model Predictive Control) is introduced. As the result of using this method, which can systemize the process from model identification to the mapping of the model parameter, high environmental performance and efficiency are achieved.
