This paper investigates an H static output feedback for a low-frequency (LF) networked control system (NCS). A decentralized event-triggered scheme (DETS) is proposed to reduce the network communication loads. The LF NCS with the DETS is modeled as a time-delay system with an LF constraint. With this model, H performance analysis is developed via an LF integral quadratic constraint method and a generalized Kalman-Yakubovich-Popov lemma. Furthermore, a detailed controller design algorithm is presented to obtain an H static output feedback controller for the LF NCS with the DETS via a two-stage approach. The numerical results are provided to demonstrate the effectiveness and superiority of the proposed techniques.
本文研究了一种用于低频网络控制系统（NCS）的H静态输出反馈。提出了一种分散式事件触发方案（DETS）以减少网络通信负载。具有DETS的低频NCS被建模为具有低频约束的时滞系统。基于该模型，通过低频积分二次约束方法和广义卡尔曼 - 亚库博维奇 - 波波夫引理进行H性能分析。此外，还提出了一种详细的控制器设计算法，通过两阶段方法为具有DETS的低频NCS获得H静态输出反馈控制器。给出了数值结果以证明所提技术的有效性和优越性。
