Stability of control systems under aperiodic sampling and input saturation withclock-dependent Lyapunov functions

International audienceIn this work, a new method of stability analysis of sampled-data control systems withinput saturation is proposed. With the use of a class of time-dependent Lyapunov functions, thecontinuous and discrete dynamics of the system are taken into account to assess the stability ofthe closed-loop system when aperiodic sampling is considered. Considering a particular quadraticform of this class of Lyapunov functions, new conditions to estimate the region of attraction ofsuch nonlinear systems are derived
