I have a question that says:
A system has the transfer function
G1(s) = (k1)^2/(s^2+2(k2)s+(k1)^2
Where k1 = 9 and k2 = 1
The tells me to write this transfer form into polynomial form and pole-zero form
I substitued the k1 and k2 into the equation to get
G1(s) = 81/(s^2+2s+81)
I think that is the polynomial form, Im just struggling on putting it into pole-zero form
Any help will be much appreciated
Kind regards,
James

The Control System Toolbox tf and zpk functions could be helpful.
