Switched/hybrid systems are dynamical systems that combine continuous dynamics and discrete events. Such systems are of theoretical interest and important in many applications, and they have attracted considerable attention in the control literature. This advanced graduate-level course will introduce the students to analysis and design of switched and hybrid systems. The selection of specific topics is heavily influenced by the research of the instructor and his collaborators, drawn from his 2003 research monograph and more recent research articles.
Instructor: Daniel Liberzon.
Office: 144 CSL.
Email: liberzon at illinois.edu
Office hours: TBD
The course will build on a standard
first-year graduate course in state-space linear systems, such as
Some knowledge of nonlinear system analysis techniques (such as those covered in ECE 517 or ECE 528) is a plus but not a requirement.
Required text: D. Liberzon, Switching in Systems and Control, Birkhauser, 2003. Available in UofI bookstore, on Amazon.com, and through SpringerLink here (university login required). The textbook material will be supplemented by recent research articles.
Final project: This course will involve a final project presentation towards the end of the semester. Details will be explained in class. There will be no required homework or exams.
