A Program to calculate value of PI


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 …

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 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 …

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 …
