Very recently I was attending an online programming course and the Instructor happened to ask a question, How man of you have ever written a program to calculate value of PI ?What has happened to the world ? In our days students used to attempt at least 2-3 algorithms to find value of PI. It …

Prepaid Manager App in Ubuntu
It was only today that I put into use my Huawei E303C modem into use. I had not used it for almost 6 months. And today I plugged it in it with the IDEA 3G sim on Ubuntu 13.04. The Huawei linux drivers almost gave me a headache and finally to get the device working …
Thats How We C
Two and a half years back, while I was still In college that I got this idea to write a book on Programming. By then I had spent almost 4 years learning and coding a couple of programming languages. I knew I was not an expert in the field, but I also knew that I …
Sharing Internet over Wifi Between Ubuntu and Android
I searched the internet alot for a solution to connect my PC's internet to my android phone by creating a hotspot. In windows you have softwares like connectify to make your life easy, But in linux things are not so easy, and I was never a windows guy. I hated to logon to windows just …

The Step response of an RLC circuit in State Space Model
This will be my last post in this series on using matlab for designing the compensators. In this post we will see the step response of an RLC circuit using a matlab program.The initial conditions are current is 1ma and voltage across capacitor is 2V. The state space representation of the above circuit is. Here …

Lead Compensator design with Root Locus
This has been the most difficult part for me since I started writting this series. I took one whole day to figure out how to write a program to designa lead compensator with rot locus in matlab. For those who have followed my previous posts will know by now what the compensators are. As said …
Lead Compensator design with Bode plot
Introduction to Matlab Lag Compensator with Bode Plot Lag Compensator with root locus So far we have seen the design of lag compensators, now we move on to lead compensators which help in improving the transient response. We will start from the frequency domain design using bode plot. Here I would like to tell the …
Lag Compensator design with Root Locus
So far we have discussed on an Introduction to Matlab and Lag compensator design with bode plot. In this post we will deal with lag compensator design with time domain specifications and using the root locus technique. The steps to design the lag Compensator are Draw the root locus of the given open loop uncompensated …
Lag Compensator design with Bode plot
In the previous post An Introduction to compensator Design with matlab we saw an introduction to compensators. In this post we will deal with lag compensator design with frequency domain specifications. The steps to design the lag Compensator are Determine K from the error constatns given Sketch the bode plot Determine phase margin if it is not …
An Introduction to compensator Design with matlab
This will be a series of posts where I will be dealing with Control system Compensator design using matlab. This is intended primarily for Btech Electrical and Electronics students. I will try to be as brief as possible the underlying concepts have to be studied from standard text books. If there are any mistakes please …
