Decentralized Stabilization for Switched Large-Scale Nonlinear Systems via Sampled-Data Output Feedback

초록

This study investigates the output feedback sampled-data stabilization problem of a class of switched large-scale non-linear 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 sampleddata 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.
