Objectives and competences

Students will acquire elementary knowledge about regulation and optimal control of linear and non linear systems (discrete and continuous), and some skill how to solve this problems with program Matlab.
They will be able to use the acquired knowledge at posing and resolving problems that appears in practices, such as, mechanics, environment sciences, and economics.

Intended learning outcomes

Knowledge and understanding:
Knowledge and understanding of the basic concepts of control of the systems.
Capacity to connect their mathematical knowledge and programming in Matlab, and to implement developed methods in natural sciences and technics.
Application:
Modeling and control of systems is one of the basic subjects necessary to understand mechanics and other subjects of biological, technical and social sciences. Knowledge is necessary in modeling of almost all systems.
Reflection:
Integrating theory and practical applications in solving problems.
Transferable skills:
Posing a problem, selection of a method and its application in solving the problem. Analysis of the results from the cases. Skills in using literature. Knowledge is transmitted to virtually all sciences.

Learning and teaching methods

Lectures, exercises, homeworks, consultations

Assessment

Type (examination, oral, coursework, project):
positive mark on the project (seminar) is precondition to seed the theoretical part of the exam.
oral exam
Grading: 1-5 (fail), 6-10 (pass) (according to the Statute of UL)
