Data-driven computational methods for the domain of attraction and Zubov's equation

W Kang, K Sun, L Xu - IEEE Transactions on Automatic Control, 2023 - ieeexplore.ieee.org
This article deals with a special type of Lyapunov functions, namely the solution of Zubov's
equation. Such a function can be used to characterize the exact boundary of the domain of …

The observability in unobservable systems

W Kang, L Xu, H Zhou - 2022 IEEE 17th International …, 2022 - ieeexplore.ieee.org
In this paper, we introduce the concept of observability of selected state variables for
systems that may not be fully observable. For their estimation, we introduce and exemplify a …
