Stability Analysis and Estimate of Domain of Attraction for a Class of Nonlinear Time-varying Delay Systems
一类非线性时变时滞系统的稳定性分析与吸引域估计

The stability and estimate of domain of attraction are studied for a class of nonlinear time-varying delay systems. Firstly, an equivalent form is obtained for the systems by means of coordinate transformation and orthogonal decomposition of vector fields. Then, based on the orthogonal condition and the free-weighting matrix method, several less conservative results are derived on the stability and estimate of domain of attraction. Finally, illustrative examples show effectiveness of the proposed method.
