The figure below shows a block diagram of a closed-loop system.Д®xamples of Closed-Loop System Air Conditioner (AC) The closed-loop systems are parameter-based control systems. The controller is designed to minimize the error as small as possible. The feedback path has a sensor that senses the output, feeds the output back into the system, compares it with the reference input, and then generates an error signal. The feedback path in the system helps to reduce the noise and disturbance a lot. The closed-loop system is a feedback control system where is output is again fed back to the input and the control action is dependent on the desired output of the system.

They have a slow response and are less accurate.ДЄ closed-loop control system works by automatically controlling a process variable.

The disadvantages of an open-loop system are as follows:

Proper calibration of the system is not a consideration making its design simple.

It is an economical system with very little maintenance required.

The advantages of an open-loop system are as follows: Here the machine operates only on the time, not on the cleanliness of the cloth is not considered as this feedback is not taken by the system. The washing machine is an example of an open-loop system that operates based on operating time. This is an open-loop system where the traffic lights are controlled or operated based on time. The open-loop systems are time-based controlled systems.Д®xamples of Open-Loop System Traffic Light Controller It is desired to use an open-loop system if we have the proper knowledge of the relationship between the input and the system. The output is not measured nor sent back to the input for additional evaluation in open-loop systems. Open-loop systems are typically used for controlling systems that rely on input or a controller. Here we will be discussing the two basic types of the control system and they are as follows: 1) Open-Loop Control System

The feedback in the system can be positive feedback or negative feedback. The value sensed by this sensor is fed to the error detector. x) FeedbackДЄn output transducer is placed in the feedback path which senses the actual output of the system. The controller varies or manipulates the manipulated variable in order to affect the value of the controlled variable. This is the quantity that is to be measured and controlled. This is the part of the system which helps in controlling application. The plant or process is also called a controlled system. A common example of a noise signal is the presence of noise in the op-amp. This unwanted signal affects the system output. These are the unwanted signals present in the system. Generally, Op-amp, relay, filter circuit are used as a controller. The controller helps in regulating the error signal generated by the error detector. Our main goal is to minimize the error as minimum as possible. Here we will be discussing each element of the block diagram.Д®rror detector produces an error signal by comparing the actual output and the desired output. The figure below shows the basic block diagram of the closed-loop control system.

The quality of the goods produced also increases with the aid of a control system.Due to quicker, faster, and accurate responses, productivity in work increases.Its application in the industries reduced the cost per product.The importance of the control system can be summarized as: In modern days and day to day applications, the control system has a great advantage and importance.
