Abstract(in English) In order to stabilize wireless networked controlled systems (WNCSs) whose components are connected through wireless networks, it is necessary to establish highly reliable wireless connections in terms of packet loss rates and packet delivery delays. In this paper, we consider a WNCS with one controller and several controlled objects, which are connected through a TDMA (Time Division Multiple Access)-based multihop wireless network. By means of the TDMA-based packet transmission, we can avoid packet losses due to collisions and guarantee the end-to-end delivery delay. In TDMA, each link on established paths is allocated to a time slot, which is referred to as link scheduling, and packets are transmitted on the link at the allocated time slot. In this paper, to stabilize the WNCS against packet losses caused by bit errors on wireless links and packet delivery delays, we propose an adaptive packet transfer scheme, where paths and link scheduling are adaptively changed according to states of the paths and the controlled objects. We evaluate the proposed scheme by simulation experiments.
