Feedback in Control Systems

In daily life we use this word feedback when we want any review or opinion or any suggestions about us or our work. So basically feedback is returning the output (with some function on it) back to the input. This feedback is the core component in any Control System.

We know that if we have a system which gets some input, process on it according to its transfer function and then give output. Now if this output has no implications on input or we say input is not governed by the nature of the output then the system would not be giving actual desired result as it is needed.

Types of Feedback in Control

There are two types of feedback used in control systems.

1. Positive Feedback
2. Negative Feedback

Both Feedbacks have their own importance in typical applications.

Control Systems Engineering

What is Control?

If we are able to get any desired behaviour from any system whether its machine or a software system or any thing, we say that we have control on it.
This is the basic theory and motto of the control systems. The control system is actually a system which provide us opportunity to get desired output by applying desired input. The desired output can be the Toast out of the Toaster at right time or it can be the angle of the radar by just moving the adjustment knob from the Control Room. Or it may be 3-dimensional air navigation and control system for the air planes or it may be the ABS system of the cars. So almost in every field we need control.

The Control System Engineering has its implications in almost every Engineering fields mainly Electrical, Mechanical, Mechatronics, Automotive, Space etc.

SPAMS in Blogging

What is Spam:

Spam is a kind of message which contains abuse and abrupt data and is sent to the email addresses by the people. Spamming remains economically viable because advertisers have no operating costs beyond the management of their mailing lists, and it is difficult to hold senders accountable for their mass mailings.

But the main thing is that these spams are of no business to the users to whom they are sent and sometimes these are very irritating to them.

Web Publishing

Web Publishing stands for uploading or ‘publishing’ your website on the internet so others can view it. There are many ways of publishing our websites; if we have our own internet presence (i-e a valid internet connection with a valid IP address) we can make our own computer an internet server. We’ll however need a very fast connection to serve so many users’ requests simultaneously. So we need an alternative!

Web Hosts

A Web host is a person or a company who has very fast internet connections and very reliable computers with multi-way backups to ensure robust service. It ‘Hosts’ our websites for us, so our users can connect to those servers and view them. Normally web hosts charge us a small fee(usually $3-10 a month).But some are free too!
