Course objectiveControl systems are usually designed by assuming that the system parameters are not changing. However, in many practical applications system parameters are not constant but changes with time and this affects the control performance adversely. Control systems that have the ability to sense the changes in the system parameters and to change itself accordingly in order to maintain a certain desired performance are called adaptive. In this course, the aim is to equip students with the necessary knowledge and skills in order to be able to understand, analyze and design such systems.  
Learning outcomes
  1. A student completing the course successfully is expected to

  3. L.O.2. be able to identify (to model) systems using experimental data.
  4. L.O.3. be able to decide whether an adaptive control is a good option for a given problem.
  5. L.O.4. be able to analyse and design adaptive control systems.
  6. L.O.5. have a suitable background to follow further studies in adaptive systems.
