Research Description

Dr. Teel's research focuses on the development of feedback control algorithms for nonlinear and hybrid dynamical systems. He is a recognized expert on control problems that directly take into account actuator limitations like magnitude and rate limits. He is a pioneer in the development of novel stability analysis tools for nonlinear and hybrid systems. The applications he has worked on include drug treatment scheduling for HIV patients, online optimization of automobile engine performance, active vibration isolation technology, mobile robots, and aerospace applications.


Dr. Teel was a post-doctoral researcher at Ecole des Mines De Paris during the second half of 1992. From 1993 to the middle of 1997 he served on the faculty in the Electrical Engineering Department at the University of Minnesota. Dr. Teel joined the UCSB ECE faculty in 1997 as an associate professor and was promoted to professor in 1999. He was the director of the Engineering College's Center for Control Engineering and Computation from April 2003 to April 2005. He is the area editor for nonlinear systems and control for the IFAC journal Automatica, and a member of the IEEE Control Systems Society Board of Governors.
