Course detail

Robust and algebraic control

FEKT-NRALAcad. year: 2019/2020

The course is focused on application of algebraic theory for control circuit’s synthesis. It consists of algebraic theory, the controller designs using polynomial methods, structured and unstructured uncertainties of dynamic systems and introduction into robust control.

Learning outcomes of the course unit

The student are able to use algebraic methodes of controller design and they know how to design robust controller.


The subject knowledge on the Bachelor´s degree level is requested.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Materials for lectures and exercises are available for students from web pages of the course. Students have to write a single project/assignment during the course.

Assesment methods and criteria linked to learning outcomes

Exercises. Individual project. Max. 30 points.
Exam. Max 70 points.
The exam will be realized via Skype or Teams without the need to have students present. One student is at home, it would be difficult to ask him to come for the exam.
