Local robust stability on compact set for nonlinear systems with continuous time controller against to aperiodic sampling and disturbance

Abstract

In this study, the stability of a sampled-value control system with time-and state-dependent disturbance and aperiodic sampling is investigated. To expand the application class of the sampled-value controller, the local stability on a compact set is considered under the assumption of local Lipschitz continuity on the compact set. Because the assumption is weaker than the global Lipschitz continuity, the proposed stability analysis is applicable to a wider class of controlled systems. Global stability under the assumption of global Lipschitz continuity is also considered. The effectiveness of the derived stability condition is verified by conducting numerical simulations with some control parameters variations such as the disturbance magnitude and sample interval.
