Learning outcomes
Introductory part of the course is devoted to the basics of system modelling and simulation methods. The main part of the course is then focused on digital simulation of linear and non-linear continuous deterministic systems in both input-output and state space context. The students are also introduced into the bond graph modelling that allows to capture the common energy structure of systems from different physical domains in a unified way. Practical examples are used to demonstrate the application possibilities of MATLAB/Simulink software for various classes of nonlinear phenomena and dynamics limitations of the simulated systems.
The student gains some theoretical knowledge and practical skills from the sphere of simulation the linear and nonlinear systems. The student is also able to create not only equations which correspond with static behaviour of the system, but also the dynamic equation and is prepare to construct the Bond graph.
