Robustness analysis of electronic systems: other application conditions

We describe some application conditions to guarantee robust stability of electronic circuits represented by a linear time invariant system with parametric uncertainty. An interval matrix is used to give the parametric uncertainty. The principal motivation of this work is given by the existence of dynamic systems with parametric uncertainty in its models. In this work we make robustness analysis using the tests given in Delgado-Romero (1994, 1995, 1996). We know the stability of a continuous linear time invariant systems is given only by matrix A; if the system contains parametric uncertainty, then A can be an interval matrix A= [L, U]
