Dynamic Systems: Principles and identification introduces dynamic systems, concepts and principles, and also approaches to system identification problems. Basic terms are defined; principles and procedures of system dynamics studies are rendered; mathematical modeling of system dynamics is discussed and main characteristics of feedback are shown; time response, frequency response and stability in time and frequency domains are considered; deterministic and stochastic system simulations are introduced; state space modeling of single and multi input, single and multi output systems and also system stabilization by pole reallocation, are covered; ergodic processes modeling and simulations are investigated; and approaches to system identification problem are introduced and explained.
