Modelling and control of systems

Completed course Differential equations.

Nonlinear systems of differential equations:
phase plane, qualitative analysis, equilibrium, nullclines, limit cycles, linearization, stability.
Discrete dynamical systems:
first and second order iterative equations, logistic equation, cycles, kaos.
(project(seminar): money for the future, controlled fishery, spread of disease, wolf/moose system , extinction diabetes mode, etc)
Fundaments of the control of system:
proportional, derivative and integral feedback.
(project(seminar): heating control, fermentation, etc)
Optimal control of systems:
modeling optimal control, choice of objective function, Pontryagin maximus principle, control with minimal energy, minimal time, »bang-bang control«.
(project(seminar): hotrod problem, stopping a space ship, controlling the harmonic oscillator, etc)

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.

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.

Lectures, exercises, homeworks, consultations

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)
