A control system can be viewed informally as a dynamical object (e.g. expressed by ordinary differential equation) containing a parameter that can be manipulated to influence the behavior of the system to achieve the desired goal. A system is a thing having parts that can be considered as a single entity. The system must be defined clearly with a particular set of relationships that completely characterize the conceivable states of the system.The state of the system describes the condition(status) of the system at any time t ≥ 0 and provides information which (together with the knowledge of the equation describing the system) enables us to calculate/analyze the future behavior of the system under certain control input. In practice it is not possible to get all state variables instead we get controlled variables (outputs) which depend on someway on measured states.
