摘要：
The present article gathers the analysis of non-asymptotic convergence rates (finite-time and fixedtime) with the property of input-to-state stability. Theoretical tools to determine this joint property are presented for the case where an explicit ISS Lyapunov function is known, and when it remains in implicit form (e.g. as a solution of an algebraic equation). For the case of finite-time input-to-state stability, necessary and sufficient conditions are given whereas for the fixed-time case only a sufficient condition is obtained. Academic examples and numerical simulations support the obtained results. (C) 2020 Elsevier B.V. All rights reserved.
