Syfte

Control plays a major role in most parts of our society. In earlier courses the doctoral students have learnt how to model and understand system behaviour. The aim of this course is to teach the students how to make a system operator more reliable, in a more environment-friendly way, with better precision, or in a more economical way, in spite of external disturbances acting on the system. The word system has a very general interpretation. It can, for example, be a reactor, a heat exchanger, or a waste water treatment plant. The course teaches a systems-oriented way of thinking which the doctoral students can make use of in their future careers, independent of the actual application area. After the couse the doctoral students should be able to formulate and understand mathematical models for dynamical systems, analyse dynamical systems, and design controllers for dynamical systems. The course is divided into three modules: modeling, analysis, and synthesis. The course gives an overview of control engineering, its concepts, methods, and applications in chemical engineering.

• understand what a linear time-invariant dynamical systems is
• be able to grasp the basic concepts of control.
• understand how a dynamical system can be modeled using different model representations, for example transient responses, transfer functions, differential equations on state-space form and input-output form, and frequency responses described using Bode or Nyquist diagrams.
