What are Examples of Control Systems and How They work


A control system is a system of devices or a set of devices that manages, commands, directs, or regulates the behavior of other devices to achieve desired results. Control systems are used in various industries and scenarios, such as manufacturing, transportation, healthcare, education, and more. In this article, we will explore some examples of control systems, how they work, and what benefits they bring.

1. What is a Control System?

A control system is a system that monitors and adjusts the behavior of other devices or systems to achieve desired results. A control system can be computerized, electromechanical, or mechanical, depending on the type and complexity of the devices or systems involved.

A control system typically consists of three main components: a sensor, a controller, and an actuator. A sensor measures the current state of a device or a system, such as its position, speed, temperature, or pressure. A controller compares the measured value with a desired set point or target value, and determines the appropriate action to take. An actuator executes the action, such as moving a lever, turning a valve, or switching a circuit.

A control system can be classified into two types: open-loop and closed-loop. An open-loop control system does not use feedback from the output to adjust the input, and operates based on a predetermined sequence or program. An example of an open-loop control system is a washing machine that runs for a fixed amount of time regardless of the load size or dirtiness. A closed-loop control system uses feedback from the output to adjust the input, and operates based on the difference between the actual and desired output. An example of a closed-loop control system is a thermostat that turns on or off the heater based on the room temperature.
