Anotace:

The course provides a basic knowledge on formulation and computer implementation of dynamical system models. It starts from theoretical issues of Laplace and Z transform in their application to describing the continuous and discrete linear systems respectively including the systems with distributed parameters. In the second part of the course particular emphasis is given on the skills in describing the dynamic processes in the state space approach in both linear and non-linear systems. A special part of the course is devoted to the system parameter optimization methods.
