dynamic output feedback control of systems with event-driven control inputs

Science China(Information Sciences) 2020年第5期63卷 24-37页

作者： Jinhui ZHANG Hao XU Li DAI Yuanqing XIA School of Automation Beijing Institute of Technology

In this paper, a dynamic output feedback control problem is investigated for systems with eventdriven control inputs. With both continuous and sampled output measurements in the systems, two types of dynamic output feedback controllers are designed based on a predefined event-driven scheduler for the control signals, respectively. With the proposed event-driven control scheme, the Zeno behavior can be avoided, and the states of closed-loop systems are also guaranteed to be globally uniformly ultimately bounded. Detailed parameters of the event-driven controllers are constructed under the stabilizable conditions of the closedloop systems. Finally, both the effectiveness and merits of the proposed design techniques are verified by the numerical examples.

This paper investigates the H∞ consensus problem for networks of multi-agent systems subject to external disturbances. In particular, a distributed dynamic output feedback controller with time-varying delays is provided, which is based on the relative outputs of neighboring agents. By using Schur complement lemma, Newton Leibniz formula and Jensen’s inequality, sufficient conditions are derived to guarantee the H∞ consensus under an undirected communication topology, which is in terms of linear matrix inequalities（LMIs）. And meanwhile the parameter of controller is also determined. Finally, a numerical example is presented to illustrate the effectiveness of the proposed methods.

This paper is concerned with the dynamic output feedback H∞ controller design for a class of nonlinear continuous-time systems with nonlinear uncertainties. The resulting design is such that the closed-loop system not only is asymptotically stable, but also meets the prescribed H ∞ norm constraint. What’s worth mentioning is that the paper proposes a new method which combines S-procedure approach to solve the nonlinear uncertainties. A sufficient condition for the existence of such a controller is obtained by using appropriate Lyapunov functional and linear matrix inequality （LMI） technique. In addition, based on this result, a convex LMI-based optimization method is developed to optimize the H∞ performance. A numerical example is provided to demonstrate the effectiveness of the proposed design.

This paper studies event-triggered output-based security control of nonlinear system under deception attacks obeying a Bernoulli distribution. Firstly, to save system resources of a T-S fuzzy system, an output-based discrete event-triggered mechanism（ETM） is introduced, which excludes Zeno behavior absolutely. Secondly, a closed-loop T-S fuzzy system model is built, which integrates parameters of the nonlinear plant, the ETM, stochastic attacks, fuzzy dynamic output feedback controller and network-induced delays in a unified framework. Thirdly, sufficient conditions for asymptotic stability of the T-S fuzzy system are derived, and the design method of a fuzzy output-based security controller is presented. Finally, an example illustrates effectiveness of the proposed method.
