## Aim

The aim of the course is to give knowledge about the basic principles of feedback control. The course will give insight into what can be achieved with control, and the possibilities and limitations. The course covers linear continuous-time systems.

## Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to define the fundamental concepts of control
• be able to linearise nonlinear dynamical models
• be able to compute the relations between dynamical models in the form of transient responses, transfer functions, differential equations on state-space form, and frequency responses described with Bode or Nyquist diagrams
• be able to analyse dynamical systems with respect to stability, robustness, stationary characteristics, controllability, and observabilility
• be able to implement controllers using discretization of analog controllers

Competences and skills
For a passing grade the student must

• be able to design controllers from given specifications on robustness and performance based on models on state-space form, transfer function form, Bode diagrams or Nyquist diagrams
• be able to design controllers based on cascade connections, feedforward, and delay compensation
• be able to evaluate controllers by analysing transient and frequency responses, and via laboratory experiments on real processes

Judgement and approach
For a passing grade the student must

• understand relationships and limitations when simplified models are used to describe complex dynamical systems
• show ability for teamwork and collaboration at laboratory exercises
