Course description:

The aim of this course is to introduce the student to the area of nonlinear control systems, that is control systems characterized by the presence of a nonlinear element, which can either be the system under control or the controller itself, including sensors and actuators.

Some classical as well as modern analysis and controller design methods for nonlinear systems will be covered so as to enable the student to appreciate the diversity of phenomena that arise in nonlinear systems and to address a significant class of analysis and control design problems in a nonlinear context.

 

The course comprises lectures and specific sessions with numerical examples.

It is structured in two parts, the first one dealing with analysis and the second one with design.

 

Part 1: Analysis of nonlinear feedback systems

- absolute stability of Lur’e systems

- switching systems stability

- input-output stability

- passivity-based analysis

- existence and stability of periodic oscillations

 

Part 2: Nonlinear control design

- variable structure control

- feedback linearization

- switching control
