syms s d e
y=((0.005659*s^2+0.05206*s+0.004496)/(s^3+9.357*s^2+2.228*s+0.06147))*((27.5084*d)+(27.5084*(e/s)))
using feedback(y,1,-1) is giving me a error, what is wrong here

You need to work with model objects, they must be either continuous os discrete with identical sample times.
Here, please read the documentation about the command feedback, which also includes some examples:
Hope it helps!

The Control System Toolbox does not support operations on sym objects. Having siad that, the error message that I'm seeing is fairly opaque, something about "not enough input arguments," which isn't very helpful.
