Definitions and Concepts t l t d i h bj ti f t ti t l d i i t Control system design: The objective of an automatic control design is to influence a system in such a way that it performs satisfactorily the tasks presented by the designer. Definition: A system is an arrangement of components connected together acting as a unit Definition: A control system is an arrangement of components connected in such a way as to command itself or another system Examples: Temperature control in a room, an autopilot of an airplane, control of a distillation column, population of a species (fish, mosquitoes), price control A control system is defined by the relation between its input and output signals. In control system terminology these signals are referred to as manipulated and controlled variables
Representation of Control Systems A control system system is schematically defined by a functional diagram that denotes the relationship between input and output signals. Note: Functional diagram represents a flow of information and not operation on any physical quantity Flow of information System Input Output m c (manipulated variable) (controlled variable) Functional Diagram
