Abstract :
We propose a method for analyzing robust stability of linear systems subject to parametric time-varying uncertainties. Using a previously developed analysis tool, quadratic separator, a less conservative upper bound on the real μ is given first. Based on this result, a sufficient condition for robust stability is given in the frequency domain. Relations to quadratic stability are discussed
