This paper is concerned with the problem of decentralized event-triggered dynamic output feedback control for large-scale systems with unknown interconnections. By using a modified cyclic-small-gain condition and introducing a free-matrix-based integral inequality, a novel sufficient condition is derived to ensure that the overall closed-loop system is asymptotically stable with a prescribed H performance. Based on this condition, a convex condition is presented to design the controller gains and the event-triggered parameters simultaneously. In contrast with the existing event-triggered results, the derived stability criterion can be applied to the large-scale systems with unmatched unknown interconnections. The effectiveness of the proposed control strategy is demonstrated by a double-inverted pendulum model.
本文研究了具有未知互联的大规模系统的分散事件触发动态输出反馈控制问题。通过使用改进的循环小增益条件，并引入一个基于自由矩阵的积分不等式，推导出一个新的充分条件，以确保具有给定 H 性能的整体闭环系统渐近稳定。基于这个条件，提出了一个凸条件来同时设计控制器增益和事件触发参数。与现有的事件触发结果相比，所提出的稳定性判据可应用于具有不匹配未知互联的大规模系统。通过双倒立摆模型验证了所提出控制策略的有效性。
