Finite-time stabilization for uncertain nonlinear systems with impulsive disturbance via aperiodic intermittent control.

• This paper considers the finite-time contractive stabilization for impulsive systems with time-varying parametric uncertainties. • A class of aperiodic intermittent controller involving uncertain impulsive disturbance is designed. • In the framework of finite-time, relationships between impulsive disturbance, aperiodic control periods, and widths are established. This paper ensures finite-time stabilization (FTS) and finite-time contractive stabilization (FTCS) for impulsive systems with time-varying parametric uncertainties by investigating the design of an aperiodic intermittent controller, where uncertain impulsive disturbance is generated at the instants caused by the control action to the plant. Based on the Lyapunov methods, several sufficient conditions are proposed to guarantee the FTS and FTCS. In the framework of finite-time, two relationships between impulsive disturbance, aperiodic control periods, and aperiodic control widths are established to guarantee the FTS and FTCS for the system, respectively. Moreover, such two relationships can potentially increase the freedom of the designed control periods and control widths. Finally, two numerical simulations and a practical application are given to show the validity of the aperiodic intermittent controller. [ABSTRACT FROM AUTHOR]
