Control Of GDI Engines using Torque Feedback Exemplified by Simulations

Summary, in English

A novel approach to the control of a GDI engine is presented. Thecontroller consists of a combination of subcontrollers, where torquefeedback is a central part. The subcontrollers are with a fewexceptions designed using simple linear feedback and feedforwardcontrol-design methods, in contrast to traditional table-based enginecontrol. A silent extremum-controller is presented. It is used tominimize the fuel consumption in stratified mode. The controller hasbeen evaluated with good results on the European driving cycle using adynamic simulation model.
