Content and learning outcomes

Course contents

Linear control systems: reachability, observability, stability, realization theory, minimality, feedback, pole-assignment, observers. Linear-quadratic optimal control, matrix Riccati equa­tion and theory for the algebraic Riccati equation. Kalman filtering.

Intended learning outcomes

The overall goal of the course is to provide an understanding of the basic ingredients of linear systems theory and how these are used in analysis and design of control, estimation and filtering systems. In the course we take the state-space approach, which is well suited for efficient control and estimation design.

To pass the course, the student should be able to do the following:

  • Analyze the state-space model with respect to minimality, observability, reachability, de­tectability and stabilizability.

  • Explain the relationship between input-output (external) models and state-space (internal) models for linear systems and derive such models from the basic principles.

  • Derive a minimal state-space model using the Kalman decomposition.

  • Use algebraic design methods for state feedback design with pole assignment, and construct stable state observers by pole assignment and analyze the properties of the closed loop sys­tem obtained when the observer and the state feedback are combined to an observer based controller. Apply linear quadratic techniques to derive optimal state feedback controllers. Design a Kalman filter for optimal state estimation of linear systems subject to stochastic disturbances.

  • Solve the Riccati equations that appear in optimal control and estimation problems.

  • Apply the methods given in the course to solve example problems, including to use the Con­trol System Toolbox in Matlab.

  • Integrate the tools learnt during the course and apply them to more complex problems.

  • Explain how the above results and methods relate and build on each other.

  • Explain the mathematical (mainly linear algebra) foundations of the techniques used in linear systems theory and apply those techniques flexibly to variations of the problems studied in the course.

  • Solve fairly simple but realistic control design problems using the methods in the course.
