Abstract

A promising method for enhancing automotive internal combustion engine efficiency uses solenoid actuators to directly control gas exchange valves. Mitigation of valve seating velocities is challenging due to phenomena such as magnetic saturation and pressure disturbances. Modeling, control design, and experimental and simulated results using a magnetic flux based sensor will be given. Flatness based motion control and pressure disturbance estimator results for both simulation and on the experimental testbed will be presented.

Biographical Information

C.R. Koch received his B.S. degree in mechanical engineering from the University of Alberta, Edmonton, Canada in 1985, and his M.S. and Ph.D. degrees from Stanford University, Palo Alto, CA, in 1986 and 1991, respectively. From 1991 to 1992 and from 1994 to 2001 he worked at Daimler-Benz/ DaimlerChrysler in Stuttgart Germany in advanced internal combustion engines. During 1992 to 1994 he worked for General Motors. In 2001, he joined the Mechanical Engineering Department of the University of Alberta, Edmonton Canada, where he is an Associate Professor. His research interests include combustion engines, advanced powertrains and control of fluid systems. He is currently on sabbatical leave at IST Institute at the University of Stuttgart until June 2008.
