Learning outcomes
|
A goal of this subject is to provide an overview of technical instruments and most important methods and principles in automatic control. The subject is more practically focused and connects to the subjects Automation I and Automation II, which are on the contrary focused on building up theoretical basis. The field of sensors is not covered, because it is included in another subject (Sensors and measuring non-electical quantities). The student obtains a view on the field from a practical viewpoint and will be prepared for designing control systems in practice and for studying specialized literature.
The graduate obtains a view into the field from a practical viewpoint.
