Abstract :
The currently proposed techniques to perform frequency-domain stability analysis against real parametric variations fail, because “discontinuities” of the real stability margin prevent straightforward frequency gridding techniques to work properly. In this paper, we present new robustness indicators that consistently detect these discontinuities
