Program Plan Intro

Control systems:

  • A control system refers to a system that is capable of managing, commanding, directing, or regulating the behavior of other machines or devices.
  • Generally, a feedback controller is used for controlling a process or operation automatically.
  • It has a wide range of applications including home heating controller, industrial control systems and many such.

On/off control:

  • The on/off control makes use of a feedback controller which switches abruptly between two states.
  • It is used to keep the final control element in the system in either on or off state.
  • A simple bi-metallic domestic thermostat can be related as an on-off controller.

Proportional control:

  • Proportional control refers to a linear feedback control system.
  • It is used to keep the final control element in intermediate positions between the on-off controls.
  • It is more complex than an on-off control system.
  • Examples of proportional controller include toilet bowl float proportional value and fly-ball governor.
