Good evening everyone,

Would it be possible to have some help for this exercise please?

Let a system whose transfer function H (p) is expressed:

1) Express the gain and the phase in the sense of Bode.

2) What is the system?

3) What is the static gain of the system worth?

4) Explain the influence of the coefficient m on the behavior of the system.

And here is what I said:

1)

with

We can deduce that .

But I don't know how to calculate the module of ,I think than

is a constant,unless the constant is that we multiply by p.

So =arg(1)-arg()=-arg()

2)This system is a order 2 system .

3)The static gain it's the gain when the time t tends to(move towards) infinity .

But my gain is not good and we have no "t" .

4) m it's the coefficient of amortization,it's all I know.
