Types of Control System
There are two types of control systems:
- Open-loop control system.
- Closed-loop control system.
1. Open-Loop Control System
In this type of control system, the system responds without considering what the output is and doesn’t continuously monitor the system’s behavior. They are used in the systems where the output is already known and predictable so that there were no errors in the system in the future. The controller in the system sends commands to the plant without receiving feedback about the actual output and thus do not consider what is the output. They do not have complex design like closed-loop systems. Open-Loop Control System are used in applications where there is no feedback and error handling are required because they do not have feedback sensors and controllers to control the system and since there are no feedback to control the system, it often makes mistakes under changing conditions. They are used in system like electric bulb, micro-ovens, traffic signals and etc.

2. Closed Loop Control System
In this type of system, the output is monitored continuously and can be adjusted whenever there is a need of it. The feedback mechanism helps to adapt to varying conditions and maintain the system in a stable state. They are used in voltage stabilizer, thermostat heater and etc. They have a very complex design as compared to open-loop control system.

Components of Control Systems
With the advancement of technology, Human dependency on control system have increased over years and are being used everywhere, playing significant role in our daily lives. Contributing to different applications, they made the work easier by reducing human effort and involvement. They are used to control the behavior of devices and systems to accomplish the desired task. Control system consist of different components which play significant role and work together to produce the desired output. Some of the major components of control system are controller, sensors and actuators. Sensors are used to convert physical changes into electrical signals. Controllers are used to adjust the functions in control system to get the desired result. In this article we will see the components of control system which made a complete control system and how they work simultaneously to produce output.
