摘要
We consider robustness of exponential stability of time-varying linear systems with respect to structured dynamical nonlinear perturbations. Sufficient conditions in terms of L-2-stability are derived. It is shown that the infimum of the complex stability radii of a family of time-invariant linear systems provides a good estimate for the stability radius of a linear time-varying system if time variations are sufficiently slow.
