Course detail
FSI-VDRAcad. year: 2024/2025
The course is focused on the deepening and application of the theory of differential and difference equations in the theory of regulation. In this course, emphasis is placed on specific applications of these equations in the theory of continuous and discrete control, including their demonstrations in the Matlab environment. The content of the course is the use of Laplace and Z-transform. For clarity, the tasks will be solved and simulated in Matlab.

Entry knowledge
Differential and integral calculus of a function of one variable, Differential equations, Difference equations, Linear continuous and discrete control, Matlab.
Rules for evaluation and completion of the course
The condition for awording assessment is active participation in exercises and elaboration of the assigned example (resp. students can choose their own example), on which the student demonstrates different methods (including computer processing) and evaluates their effectiveness.
The examination is written and oral. In the written part the student solves two basic topics (differential and difference equations). The oral part of the exam contains a discussion of these tasks and possible supplementary questions.
Attendance at seminars and lectures is mandatory, due to the close interconnection of their content. Absences can be compensated by assigning substitute tasks.
Aims
The aim of this course is to apply ordinary differential and difference equations in control theory. Furthermore, the subject is an effort to expand and connect knowledge in the field of solving differential and difference equations, Laplace transform, Z-transform and transfer theory. The purpose of the course will also be to solve and simulate tasks with the support of the Matlab program.
By completing this course, students will not only deepen their knowledge in the field of differential and difference equations, but they will get acquainted with applications and various solutions, including their advantages and disadvantages (classical mathematical approach, Laplace transform, Z-transform, Matlab).
