Dear all
I have a problem with my project i want to control the noise with using
the adaptive filter(LMS)in matlab simulation block i get a good result
with my transfer function when i used C= -H/G in the fix controller but
after i substitute the fix controller with adaptive controller then my
results didn't converge my questions is:

1-how can i define the desired in put when i use the transfer function
blocks  here i have H,G transfer functions 

thanks
