| 中文摘要 |
| 本文研究了在拒绝服务攻击下网络化非线性系统的采样数据输出反馈控制问题. 首先, 为了避免使用完整
的状态信息, 在存在拒绝服务攻击的情况下设计了一种新颖的切换观测器. 其次, 同时考虑两个采样周期和拒绝服
务攻击的影响, 建立了一个新的切换增广系统模型, 包括系统本身和误差系统. 利用该模型和分段Lyapunov-Krasov-skii泛函方法推导出保证切换增广系统是指数稳定的充分条件. 进一步, 利用线性矩阵不等式的解给出了观测器和控制器增益的共同设计方案. 最后, 通过仿真验证所提出控制方法的有效性. |
| 英文摘要 |
| This paper studies the sampled-data output feedback control problem for networked nonlinear systems under
denial-of-service attacks. First, to avoid using full state information, a novel switched observer is developed in the presence
of denial-of-service attacks. Second, a new switched augmented system model, including the considered system and the
error system, is established by considering the effect of two sampling periods and denial-of-service attacks simultaneously.
By virtue of this new model combined with a piecewise Lyapunov-Krasovskii functional method, the sufficient conditions
are derived to guarantee exponential stability of the resulting switched system. Furthermore, the co-design method of
observer and controller gains is given by a solution of linear matrix inequalities. Finally, simulation results are presented to
verify the effectiveness of the developed control method. |
