MANCILLA AGUILAR, J. L.  and  GARCIA, R. A.. Stability analysis of a certain class of time-varying hybrid dynamical systems. Lat. Am. appl. res. [online]. 2003, vol.33, n.4, pp.463-468. ISSN 0327-0793.

In this work we study the exponential stability of a class of hybrid dynamical systems that comprises the sampled-data systems consisting of the interconnection of a time-varying nonlinear continuous-time plant and a time-varying nonlinear discrete-time controller, assuming that the sampling periods are not necessarily constant. For this purpose we develop an Indirect Lyapunov Method of analysis, and show that under adequate hypotheses the exponential stability of the hybrid dynamical system is equivalent to the exponential stability of its linearization.

Keywords : Sampled-Data Systems; Lyapunov Stability; Hybrid Systems; Discrete-Time Systems.
