Aims

The aim of the course is to introduce general system theory and its application to dynamic systems and systemic approach towards control tasks solution.
After passing the course, the student is able to:
- demonstrate and explain the difference between state space and input output description of the system
- explain the concept of causality, realizability, reachability, controlability, observability and reconstructability of the system
- identify and approximate basic types of dynamic systems and discretize the system
- apply the principles of block algebra and Mason’s gain rule for the evaluation of the system’s transfer function
- design the state observer and state feedback
- explain Bayesian approach to estimation and the principle of Kalman filter
