摘要
In this paper, the singular positive system with uncertain parameters and switched structure is analyzed. First of all, a nonfragile dynamic output-feedback controller with Round-Robin protocol is constructed so as to decrease the occupancy of the communication channels and overcome the phenomenon of controller gain fluctuations. Then, the regularity, causality, positivity, and robustly exponential stability of the resultant closed-loop system are discussed respectively by utilizing the method of mode dependent minimum dwell time, mode dependent ranged dwell time, and mode dependent constant dwell time. The explicit design mechanisms of the related controller parameters are simultaneously presented. Finally, two simulation examples are provided to show feasibility of the theoretical results obtained.(c) 2022 Elsevier Ltd. All rights reserved.
