摘要
This paper is concerned with communication and control co-design for wireless sensor networked control system (WSNCS) with time-varying delay. Jointly designing communication and control is an attractive paradigm for WSNCS, since the control performance of WSNCS is high sensitive to resource-constrained communication networks. The main idea of devised scheme is searching an optimal event-triggered transmission condition on the premise that wireless link capacity constraint is satisfied and stability of systems is guaranteed. The main aim of devised scheme is to greatly optimize control performance of WSNCS. First, two wireless network architectures characterized by multi-hop and star topology are put forward. Secondly, a model of WSNCS with event-triggered transmission mechanism is constructed. It is followed by stability analysis of WSNCS to obtain the asymptotical stability condition of systems. And then a search algorithm is presented for communication and control co-design. Finally, numerical examples are given to illustrate the effectiveness of the proposed method.
