Question

What is the physical interpretation of the poles and zeros?

Answer 1

let there is a function
\[F(s)=\frac{ sE(s) }{ (s-P_1)(s-P_2)}\]
in this equation u can see when\[s=P_1 \]
or
\[s=P_2\]
then the function \(F(s)\) will become infinite or simply the function will blow out
so here P1 and P2 are the poles.
and look when
\[s=0\] or
\[s= \infty\]
then the function will simply vanish
so hete s=0 or infinity are the zeroes for which the function will vanish
hope this helps :)

Answer 2

in the analysis of Control System, the poles (usually determined at denominator of transfer function) will give you system's behavior or steady state response using the unit step function \(f(t) = u(t)\)...

Answer 3

You can also determine system's Stability...

Answer 4

i agree with orion1213 poles and zeroes are required to determine the system stabality
