Hi guys
I am just doing my lap assignment, to design a controller using QFT, i would be so grateful if someone gave me clear information about how to determine the lower and upper boundaries that represents the region of uncertainties so that I can design a controller to my plant ,, the transfer function which represents the plant is given

Thanks a lot
