Abstract

This article is committed to the matter of asynchronous dynamic output feedback control for a class of Takagi–Sugeno fuzzy Markov jump systems. The principal concept is to construct a high-level Markovian process governed controller under an asynchronous event-triggered scheme and to develop a time-varying dissipative index. As a salient feature that distinguishes it from the reported works with the common index, this paper firstly proposes a dissipative index with mode and membership functions-dependence. Secondly, governed by the high-level Markovian process, the asynchronous dynamic output feedback controller is constructed under the mode-dependent partitioned regions. Meanwhile, to mitigate the communication pressure, an asynchronous dynamic event-triggered mechanism is investigated with making allowances for the inaccessible system mode. What's more, as a first effort, this article presents a unified framework for co-designing the strategy of asynchronous event generators and controllers. This is done under the proposed performance index and the mode-dependent fuzzy state-space partitions, resulting in more design flexibility. Based on the mode and region-dependent Lyapunov functional, sufficient criteria are obtained to ensure the proposed dissipative performance and stochastic stability. Eventually, the practicabilities and advantages of the theoretic results are illustrated by a modified tunnel diode circuit model.

具有参数相关耗散性能的T-S模糊马尔可夫跳变系统的输出反馈控制
研究了一类Takagi-Sugeno模糊马尔可夫跳变系统的异步动态输出反馈控制问题。主要概念是在异步事件触发方案下构造一个高级马尔可夫过程控制控制器,并建立一个时变耗散指标。本文首先提出了一种具有模态和隶属函数依赖的耗散指标,这是区别于已有文献中使用普通指标的一个显著特点。其次,以高级马尔可夫过程为控制对象,在模式依赖的划分区域下构造异步动态输出反馈控制器;同时,为了减轻通信压力,研究了一种考虑不可访问系统模式的异步动态事件触发机制。此外,本文还提出了一个统一的框架,用于共同设计异步事件生成器和控制器的策略。这是在提出的性能指标和模式相关的模糊状态空间分区下完成的,从而提高了设计的灵活性。基于模态和区域相关的Lyapunov泛函,得到了充分的准则来保证所提出的耗散性能和随机稳定性。最后,通过改进的隧道二极管电路模型说明了理论结果的实用性和优越性。

期刊介绍: Papers that do not include an element of robust or nonlinear control and estimation theory will not be considered by the journal, and all papers will be expected to include significant novel content. The focus of the journal is on model based control design approaches rather than heuristic or rule based methods. Papers on neural networks will have to be of exceptional novelty to be considered for the journal.
