Objectives Recognize and model control systems in
mathematical framework Analyze control systems
stability performance criteria
Design control systems tools for development
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
