XCOS Second Order System with Imaginary Poles "Answer given for denominator is incorrect"
Hi there,
I am experiencing a problem with XCOS where I cannot simulate a simple second order system that has imaginary poles. I am trying to add the transfer function, H(s) = k/(s^2 + 10s + k) where k = 1, 10, 100 to a CLR box with a unit step input to determine how the system will act, but it is not working, stating "
Answer given for Denominator (s)
is incorrect: %val=[[s^2+10s+k];".
How can I get past this error and utilize xcos to work with a transfer function that contains imaginary poles?
Thanks.

Oh jeez, nevermind. I found out the problem. Xcos does not know how 10s works. I needed to add a 10*s instead of 10s. Problem solved!


I have read this book thrice in two months the only greatest thing in this book is that the author has tried to say how we are living on this earth as human and what mistakes we are doing. I keep doing australianwritingblog articles search for my college assignments and came across an article review about this book and felt interested in reading it.
