FIT Lecture Hall, Tsinghua University
Modeling and Control of Engines and Drivelines
Chair: Lars Eriksson, Linköping University, Sweden
Abstract
Engine control plays an important role in the development of clean and efficient vehicles, since it
has a direct impact on emissions and fuel consumption. The short course will give a survey of the basic
controllers that are used in an engine control system and that interacts with driveline, and three different
subjects will be covered. Firstly, attention will be given to the torque based structure. This is a structured
design methodology for transferring the drivers demand through the driveline to the engine actuators. Secondly,
basic air and fuel control for engines will covered, giving insight into the feedback and feedforward
control loops for air and fuel and their importance for achieving a clean vehicle. Thirdly, the ignition control
will be covered, highlighting the control loops for best engine efficiency and safe engine operation. Then,
two case studies will be presented. Focusing the attention on improving the performance of gasoline
engines during the transient operation stages, the first one will introduce model-based design methods
for the control issues of starting speed and air-fuel ratio under fuel injection path changing. Theoretical
demonstrations for the proposed control schemes as well as experimental validations will be shown. In the
second one, the principle and operation strategy on the whole operation range of a gasoline HCCI engine
equipped with variable valve actuation system will be introduced and some control challenges and counter
measures on a multi-cylinder engine will be discussed and analyzed.

Biography of Chair
Lars Eriksson has been an Associate Professor at Linköping University since 2003. He
was born in Edsbyn, Sweden in 1970 and received the M.Sc. degree in Electrical Engineering
1995 and the PhD degree in Vehicular Systems in May 1999 both from Link 枚 ping
University. Since then he has been employed at Vehicular Systems first as Assistant Professor
and now as Associate Professor. During 2000 and 2001 he spent one year as a
post doc in the Measurement and Control group at Swiss Federal Institute of Technology,
ETH Zurich.
