Course information

Content and learning outcomes

Course contents *

Introduction and motivation, Invariance and controlled invariance, Zeros, Zero dynamics and system inversion, Tracking and non-interacting control, Disturbance decoupling, Internal model principle, Spectral factorization, Nonlinear systems, Geometric control of robotic systems.

Intended learning outcomes *

This is an advanced course in mathematical systems theory. With the geometric control theory in focus, this course deepens and broadens knowledge and introduces new concepts in the subject. The course aims at that the student can use the geometric approach to treat basic control design and analysis problems for both linear systems and some nonlinear systems. The knowledge and skill acquired in this course also help enhance the student's ability for abstracting engineering problems.

The overall goal of the course is that the student understands and appreciates the theory and various tools in the geometric approach to systems and control; in particular the student should be able to use the underlying methodologies in practical applications.

Measurable goals

After having finished the course the student should be able to do the following:

  • Reinterpret basic control properties such as Controllability and Observability for linear systems as the property of certain invariant subspace.
  • Understand the geometric interpretation of transmission zeros and zero dynamics.
  • Compute invariant subspaces and various controlled invariant subspaces.
  • Apply different algorithms to solve control problems such as DDP, non-interacting control, tracking and output regulation.
  • Explain how the steady state output response is shaped by the input signal.
  • Solve some basic control problems for nonlinear systems that do not have a controllable linearized system.

For the highest grade the student should be in addition able to

  • Explain how the above results and methods relate and build on each other.
  • Explain the mathematical foundation and control implication of the results and algorithms studied in the course.
  • Solve simple but realistic control problems that require the synthesis of different design algorithms.
