Electrical and Computer Engineering 3330A/B Lecture Notes - Lecture 1: Cruise Control
A control system consists of subsystems and processes assembled for the purpose of obtaining a desired output with a desired performance, given a specified input. Car steering control thousands of industrial control systems quality control production control temperature control pollution control precision control robot control sophisticated physiological control schemes body temperature regulation hormone level control. Control engineering is not restricted to one field of engineering but applicable to different branches of engineering such as aeronautical, mechanical, chemical, civil, computer, electrical. Consider elevators in which the input and output of the system are simple to define. 2. passenger comfort is related to the transient response of the system passenger safety and convenience is related to the steady sate error. Major objectives for system analysis (evaluation of system performance) and design (creation or modification of system performance) are: 3. a desired transient response a desired steady-state response stability.
