Robust and Algebraic Control
FEKT-MRALAcad. year: 2017/2018
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.
