Control System

Our Take

A control system is a system that attempts to create a desired output from a wide variety of inputs, using different tools or components depending on whether the system is electrical or mechanical (such as motors, resistors, capacitors, inductors for electrical and springs, shocks, weights for mechanical, etc.) These systems can also be controlled via software not just hardware.

Book Definition

A control system is a mechanism that directs the input it receives through the systems and regulates their output.


A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large Industrial control systems which are used for controlling processes or machines.
