ABSTRACT
A dynamic system is defined as a set of components or activities that interact together to achieve a desired task. To study a system, be it a chemical plant or a flight vehicle, the first thing required is a mathematical model (as a reality with reduced complexity) that closely represents the system under study. In other words, a model is a simplified representation of a system that helps to understand, predict, and possibly control the behavior of the system. It presents knowledge of the system in usable form and can help simulate the behavior of the system.
