Remarks (specific information about assesment, entry requirements, etc.):

Goals:
The goal of the course is to provide an introduction to the basic steps of physical system modelling, model simplification and model simulation. The course discusses many example problems from the area of process dynamics, chemical processes, and dynamic mechanical systems.

Computer use:
The computer will be a key instrument in all steps of model formulation, model simulation and model approximation. The modelling and simulation exercise is an individual exercise where the student has to formulate a dynamic model on the basis of a description of the system in the form of a paper or article from the literature. Subsequently, a simulation using Simulink (or similar) is required to investigate and assess the dynamic properties and behaviour of the plant or system under study, as relevant for its operation.

Laboratory project(s):

Design content:
The goal of the course is modeling as part of a process of control system design activity.
