Abstract :
It is shown how to compute the stability margin of periodic systems with respect to compatible periodic perturbations of such systems. It is suggested that the nonstandard time-invariant model for periodic systems introduced by the author (Syst. Contr. Lett., vol.17, pp.9-14, 1991) leads to a simpler computation, although the standard model gives the same result
