Abstract
An efficient procedure is presented for computing the frequency-respon se templates of uncertain rational transfer functions depending on two independent interval polynomials. It consists of a modified Cohen-Sut herland algorithm for the intersection test of two rectangles and a pi voting algorithm. Because the proposed procedure traces out the bounda ry of a frequency-response template directly, it is, in general, more efficient than the previously proposed algorithms.
