where can i get a good material about poles and zeros....explanation in terms control systems and also in analog circuits.......
 

poles and zeros

Circuit Analysis
By
William Hyat
 

physical meaning of poles and zeros

for stable systems,pole should be in right hand of S plane (negative real value)and if it is imaginary axis(non real) ,it indicates system is oscillatory...
if it is real and imaginary( a complex),then system response is damped oscillation.....
if poles are left in Splane then system is highly unstable...

and me if u have some questions.

Concept is very simple.

When you see a pole, the output from the transfer function give you a infinite value..
WHen you see a zero, the output is 0.

hi
also I say you to see the books by:
1) Hayt
2) Dorf
3) Nelson

i want to know about the effect of addition of pole or a zero to a circuit....
 

physical significance fo poles and zeros

pole zero cancellation method can be used for cancellation techinque.........
 

explanation about poles and zeros

sedra and smith.
 

network analysis van valkenburg + rapidshare

sedra&smith is always a good book and you can find the definitions of poles and zeros and their realtion of the stability and the gain af any system in the book
 

van valkenburg rapidshare

hi,
u can read the book "Network Analysis" by Van Valkenburg.
A very good introduction to poles and zeros is given in that book

stability poles and zeros

can anyone tell me what is the physical meaning of adding a pole and zero.I want to ask what we do in reality when we say
we added a pole to the system(what change or component ve we introduced in our construction)
we added a zero to the system

Added after 20 minutes:

addition of pole makes system less stable but decreases its steady state error .
adding a zero makes the system stable but its steady state error is increased.

see ogata's control system book of kou's book

A question repeated on behalf of our friend umairmahmood and also may persons like us..

OK - here is a short explanation:

1.) Adding a pole means to have an additional factor (1+sT) in the denominator of a transfer function. This can be done by using an additional lowpass of 1st order.
2.) If (1+sT) appears as an additional factor in the nominator it acts like a zero.
This can be accomplished - for example - by adding another R in series with the cap of the low pass circuit.

Added after 18 minutes:

That´s definitely not true.
Have you ever heard about lag compensation - a method for stabilizing a circuit by adding a pole.
