Robust stability analysis for linear systems subjected to time-varying uncertainties within the framework of nest algebra
Xiaoping˙Xua,*, Liu˙Liub
ABSTRACT: In this paper, we consider the robust stabilization problem for linear systems subjected to time-varying uncertainties within the framework of nest algebra. For four types of plant perturbations, we obtain some new sufficient conditions or necessary and sufficient conditions for robust stabilization without using coprime factorization. We also give some examples to show the validity of our new results.
