Abstract
An algorithm is given for the fast computation Of the value sets of un certain transfer functions, including parametric uncertainty in factor ed real form and multiplicative unstructured uncertainty. The uncertai n parameters are assumed to belong to compact intervals. Elementary va lue sets are computed for each factor. Vector addition and edge detect ion in the logarithmic complex plane are used to compute the complete value set. The algorithm is meant for robust control system design.
