Further Results on Stability Analysis for Sampled-Data Systems via Refined Semi-Looped-Functional

This paper investigates the stability problem for sampled-data systems by adopting a refined semi-looped-functional, which is with the following two improvements. Firstly, the new functional term is with a new integral vector η₀, which contains sampling information of the systems and associates two commonly used vectors. Secondly, the vector η₀ is combined into various zero equations for processing the functional, especially where a new equation is derived from η₀. Based on the refined functional, further stability results for sampled-data systems are obtained. And the effectiveness of the results is numerically verified through two examples at the end.
