论文摘要
由无线控制系统（WCS）和移动代理系统（MAS）组成的异质系统在工业互联网（IIOT）系统中无处不在。在该系统中，移动代理的位置可能会导致无线通道上的阴影褪色，即WCS受到控制，并可能严重损害WCS的性能。本文重点介绍了MAS的控制器设计，以确保在WCS和MAS耦合存在下WC的性能。首先，采用具有配置文件依赖性开关拓扑的受限有限场网络（FFN）来进行MAS的操作控制。借助代数状态空间表示（ASSR）方法，可以为WCS和MAS耦合获得等效形式。然后，就建立了在约束设置稳定方面的必要条件，以确保具有预期衰减率的类似Lyapunov的性能。最后，提供了一种图形方法以及呼吸优先搜索，以设计MAS的状态反馈控制器。使用此方法，很容易检查MAS的约束集合稳定，并确保在WCS和MAS耦合存在下WC的性能要求。一个说明性示例的研究显示了所提出的方法的有效性。
The heterogeneous system consisting of the wireless control system (WCS) and mobile agent system (MAS) is ubiquitous in Industrial Internet of Things (IIoT) systems. Within this system, the positions of mobile agents may lead to shadow fading on the wireless channel that the WCS is controlled over and can significantly compromise the WCS's performance. This paper focuses on the controller design for the MAS to ensure the performance of WCS in the presence of WCS and MAS coupling. Firstly, the constrained finite field network (FFN) with profile-dependent switching topology is adopted to proceed the operational control for the MAS. By virtue of the algebraic state space representation (ASSR) method, an equivalent form is obtained for the WCS and MAS coupling. A necessary and sufficient condition in terms of constrained set stabilization is then established to ensure the Lyapunov-like performance with expected decay rate. Finally, a graphical method together with the breath-first searching is provided to design state feedback controllers for the MAS. With this method, it is easy to check the constrained set stabilization of MAS and to ensure the performance requirements of WCS in the presence of WCS and MAS coupling. The study of an illustrative example shows the effectiveness of the proposed method.
