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...

modern control systems dorf rapidshare

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.

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

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.

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.
