Arbitrary transfer function in simulink
显示 更早的评论
I need the transfer function with (sqrt(s)+1)/(sqrt(s)-1) to model a special device.
But all the transfer function I get is standard one, either TF or ZP expression. This is not good at all.
Do anyone know how to realize this in simulink?

Hi Yongwei,
You would need to mathematically approximate the original transfer function and express it in terms of polynomials with integer powers, which can be handled by MATLAB and Simulink.
In addition, there are two references on MATLAB Central that allow you to approximate transfer functions where the power of 's' might not be an integer:
