Definitions System: arrangement of (physical) components connected or

related to act as a whole Control: regulate, command, or direct Control System: arrangement of components to command,

regulate or direct (1) man-made, (2) natural, (3) hybrid

Inputs: excitation applied to system Outputs: response of the system subject to inputs Disturbances: external input to system that (adversely) affects

system output Open-Loop: system whose current

output is unaffected by previous outputs Closed-Loop: system in which current

output is determined from previous inputs

Mathematical Framework Dynamical systems can be described by

differential equations. Although systems are truly non-linear, lots can

reasonably be represented by linear systems
