Abstract :
Sufficient conditions are derived for the existence of a fixed coefficients polynomial c*(s) such that (c*(s))/(a(s)) is a strictly positive real (SPR) transfer function, where a(s) belongs to the set of interval stable polynomials. The design procedure is described, when these conditions are satisfied, using an illustrative example
