Abstract

This study investigates the output feedback sampled-data stabilization problem of a class of switched large-scale nonlinear systems with asynchronous switching and dead zones. Since only the system outputs are available at the sampled-data instants, a state observer is constructed to estimate the unmeasured state. To deal with nonlinear interconnections, a new decentralized sampled-data controller is designed. A novel average dwell-time constraint condition is derived to guarantee the considered system's stability in the presence of asynchronous switching. The proposed method's effectiveness is demonstrated by its application to a quadruple-tank process system.
