Automatic Control (AC) at ECE Stan Żak ECE 200 March 12, 2015

What is Control? Use of algorithms and feedback to affect the operation of physical objects/processes of interest to achieve some desired performance Environmental Perturbations User Input Controller Actuator Input Physical Objects: Plant, Process, System output Sensor

Example: Cruise Control Environmental disturbances (road condition, wind, etc.) Controller Desired speed Input Output Measured speed (throttle angle u) Sensor (speedometer) Display (speed y) Actuator (throttle) Controlled object (car) Control Problem: to maintain car speed at the desired level

Examples of Control Systems Robotics Vehicle Control Network Control Process Control Building Control (Air) Traffic Control

Control is Everywhere Electrical, mechanical, electromechanical sys. Aeronautical and astronautical systems Ecological, Biological systems Financial systems …
