Other types of controllers and regulators
Introduction
A control system is defined as a set of components that can regulate its own behavior or that of another system in order to achieve a predetermined operation.
In a control system 4 parts can be identified: Measurement, Action, Control, and Reference.
Every control system measures and does something, the process is carried out by the controller that uses programs and references (Set-point). The references or parameters are the adjustable part of the Software; they are intangible, they cannot be touched, and they need a physical support to be memorized; and Measurements, Drives and Controllers are the Hardware that can be seen and touched.
Due to our human nature, it is useful to mention manual control and automatic control:.
There are two common classes of control systems: Open-loop systems and closed-loop systems. In open loop control systems, the output does not intervene in the control action; while in closed loop systems, it is required to know the output to exercise control of the system. A closed loop system is also called a feedback control system.
Industrial control systems are generally used for industrial production processes to control equipment or machines.[1].

Classification of control systems
Contenido
Los sistemas de control pueden ser de lazo abierto o de lazo cerrado basado en que la acción de control sea independiente o no de la salida del sistema que se desea controlar.
Open loop control system
It is that system in which the output has no effect on the control system, this means that there is no feedback from said output to the controller so that it can adjust the control action.
