In this paper, we consider the event-triggered control problem for continuous-time switched linear systems. It is assumed that only the sampled information of system state and switching signal is available to the controller at each sampling instant. Based on a mode-dependent event-triggered transmission scheme, the closed-loop system is modeled as a switched system with delayed state and augmented switching signal. Then, an exponential stability condition, characterized by the dwell time and average dwell time of the switching signal, is obtained. The condition presents an extension of the multiple Lyapunov functional method based stability analysis for sampled-data control of nonswitched system. Consequently, the design methods for state-feedback controller gains and event-triggered parameters are then formulated by the properly selected quadratic Lyapunov functional. The analysis results are significant and also lead to an important step to study the event-triggered control for switched system. Finally, based on the definition of event-trigger efficiency, the effectiveness and improvement of the proposed approach are illustrated by two numerical examples. [ABSTRACT FROM AUTHOR]

Highlights • A new sampling scheme for synchronization of switched nonlinear systems is proposed. • A master-slave synchronization method for switched nonlinear systems using output sampling feedback control is developed. • The synchronizing controller can be designed by solving a set of linear matrix inequalities. Abstract This paper addresses the master-slave synchronization problem for a class of continuous-time switched nonlinear systems. The sampled-data of system output and mode is utilized to design the quantized synchronizing controller. Based on the input delay approach, the synchronization error system is modeled as a switched system with state delay and asynchronously switching signal, which generated by merging the original switching signal with its sampled data. Then by constructing an appropriate Lyapunov-Krasovskii functional, a new sufficient synchronization condition and synchronizing controller design approach for the considered switched systems are obtained. One example is given to illustrate the effectiveness of the proposed synchronization scheme. [ABSTRACT FROM AUTHOR]
