Content and learning outcomes

Course contents

The course treats control theory for nonlinear dynamic systems:

  • analysis of input-output stability by means of e.g. the small gain theorem and the circle criterion
  • analysis of stability of equilibrium points through linearization and Lyapunov methods
  • analysis of stability for passive systems
  • design and analysis of feedback control for nonlinear systems through linearization, feedback linearization and Lyapunov based methods
  • design and analysis of high gain feedback, e.g. sliding mode control
  • observers for nonlinear systems
  • setpoint regulation control and setpoint tracking
  • simulation of nonlinear dynamic models.

Intended learning outcomes

After passing the course, the student should be able to

  • formulate theory and definitions of important concepts in nonlinear control systems
  • apply theory and methods within nonlinear control.
