A control system is a set of devices and processes that work together to maintain a specific process variable within specified limits. It is made up of three main components:
Sensor: Detects a physical quantity such as temperature, pressure, or position and converts it into an electrical signal
Controller: Responsible for the performance of the control system. It is a device or an algorithm that works to maintain the value of the controlled variable at set point
Actuator: A manipulated variable 

Other components of a control system include:
Feedback: A process in which the output of a system is measured and used to correct or adjust the input to the system
Control element: Includes all components in the process control loop, as well as the control scheme implemented to regulate the process parameter 

A good control system has several essential factors, including:
Hierarchical suitability: The system must suit the organization's hierarchy
Economical control: The benefits of the system should outweigh its costs
Simple to understand: The system should be simple to comprehend and work on 

There are different types of control systems, including:
Closed-loop or feedback controller: An example of a control system
Open-loop controlled system: A control signal which is considered input is sent to a system (Source), and the system responds without considering the output
Selective control: A control system where there is one process that has two manipulated variables (measuring instruments) with only one variable control (actuator)
