Open-loop and closed-loop control systems

A system is defined as the collection of blocks connected together to execute a process. In electronic theory, a system can be said as a group of interconnected electronic devices, in which each individual system having its own input — output relation, to control the other block by connecting its output further to its next system. The control system can also be defined as the group of devices which are used to control or regulate the functioning of other system. Sometimes, to attain the consistency and stability of a system and to produce the desired output of a control systems, we use feedback loop. A feedback is nothing but a part of output signal.

What are Open Loop & Closed Loop system

One of the significant difference between the open loop and closed loop control system is that in an open loop system the desired output does not depend on the control action. While in the closed loop system the desired output depends on the control action of the system. The other differences between the open and closed loop system are shown below in the comparison chart. In closed loop, the output depends on the control action of the system. Amplifier, Controller, Controlled Process, Feedback. Air conditioner, temperature control system, speed and pressure control system, refrigerator, toaster.

Thank you for posting the great content…I was looking for something like this…I found it quiet interesting, hopefully you will keep posting such blogs…. Keep sharing. Hello amitbiswal. My Dad is an electrical engineer and also a mechanical engineer. I now know that closed loop system is more complex in design and since I am familiar with hi-tech devices as a consumer I am for the close loop system.

The behavior of the system can be determined with the help of a differential equation is known as the control system. So it controls different devices as well as systems with the help of control loops. Control systems are classified into two types like open loop and closed loop. This article discusses an overview of the difference between open-loop and closed-loop control systems. It is very simple, needs low maintenance, quick operation, and cost-effective. The accuracy of this system is low and less dependable. The example of the open-loop type is shown below.

Difference Between Open Loop & Closed Loop System

A system is a combination of a functional unit that acts together in such a manner as to achieve the desired objective. The above figure shows that the Block diagram of a representation of the system. It produces an output corresponding to a given input signal in accordance with some rule. There can be any number of input and output signals.

 - Ты уже задавал мне этот вопрос, помнишь. Пять месяцев. Я сказала. - Я знаю.

С какой стати вы решили послать туда моего будущего мужа. - Мне был нужен человек, никак не связанный с государственной службой. Если бы я действовал по обычным каналам и кто-то узнал… - И Дэвид Беккер единственный, кто не связан с государственной службой. - Разумеется, не единственный. Но сегодня в шесть часов утра события стали разворачиваться стремительно.

У нас нет времени, чтобы… - Никакая служба здесь не появится, Сьюзан. У нас столько времени, сколько. Сьюзан отказывалась понимать. Не появится. - Но вы же позвонили… Стратмор позволил себе наконец засмеяться.

Open-loop controller

 Я обошел программу Сквозь строй, - простонал коммандер.

Молодой лейтенант пустил туда Беккера по распоряжению севильской гвардии - похоже, у этого приезжего американца имелись влиятельные друзья. Беккер осмотрел одежду. Среди вещей были паспорт, бумажник и очки, засунутые кем-то в один из ботинков. Еще здесь был вещевой мешок, который полиция взяла в отеле, где остановился этот человек.

Дверь повернулась до положения полного открытия. Через пять секунд она вновь закроется, совершив вокруг своей оси поворот на триста шестьдесят градусов. Сьюзан собралась с мыслями и шагнула в дверной проем. Компьютер зафиксировал ее прибытие. Хотя Сьюзан практически не покидала шифровалку в последние три года, она не переставала восхищаться этим сооружением.

 - Он улыбнулся.  - Но на этот раз, - он вытянул левую руку так, чтобы она попала в камеру, и показал золотой ободок на безымянном пальце, - на этот раз у меня есть кольцо. ГЛАВА 116 - Читайте, мистер Беккер! - скомандовал Фонтейн. Джабба сидел весь потный, положив руки на клавиатуру.

In an open-loop controller , also called a non-feedback controller , the control action from the controller is independent of the "process output", which is the process variable that is being controlled.
