Bilinear Transformation

03/24/2009 1:39 PM

how do we change a lead-lag compensator into infinite impulse response filter?

by using bilinear transformation.

the specification given is:-

sampling frequency = 10 hz

transfer function, H(s) = (1+s)/(1+10s)

and assuming fo = 1 hz

i hope everyone won't mind my question. because i'm trying to check whether what i'm doing is correct or not.

So many read it, but less people like to help with it?

I try,

At first, you should make sure your description is clear. what is fo? if you define sampling frq. the time T will be 0.1S at your description.

z = e^0.1s use this for your digitalization.

next, your equation is stable, neednt any compensation.

the third, as an exercise, your can choice another TF for bilinear transform.

and we have to know where is switcher?

hope this will be helpped.
