Dynamic Control Approach for Network Systems under Event-triggered Communication with Dual Triggers
Yuchao Guo,Cheng Song,Yuan Fan 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.11
This work studies the event-triggered control problem for networked control systems. The plant is controlled directly by a dynamic local controller, which receives the reference control signal from the remote controller. The measurement signal of the plant and the reference control signal of the remote controller have their separate event triggers, and thus the remote controller and the local controller can decide when to transmit signals on their own. It is proved that with the proposed control approach and the dual event triggers, the closed loop system is globally asymptotically stable, which has been illustrated by simulation results.

In this paper, we characterized a differentiallyexpressed receptor-like cytoplasmic kinase XCRK, whichconfers resistance to bacterial leaf streak (BLS). We analyzedthe tissue expression of XCRK and showed that XCRK waswidely expressed in multiple rice (Oryza sativa) organs,including internodes, roots, leaves and flowers. In addition,the expression of XCRK was significantly induced by ABA,salt and H2O2 treatments, suggesting its function in thesepathways. The XCRK-overexpressing transgenic seedlingsexhibited higher tolerance to Xanthomonas oryzae pv.oryzicola(Xoc) compared with the wild-type seedlings. Furthermore,XCRK-overexpressing seedlings showed stronger antioxidantcapacity with reduced MDA and H2O2 content and higherantioxidant enzyme activities. It has been hypothesized thatthe enhanced Xoc tolerance was attributed to the improvedexpression of resistance-responsive factors positively regulatedby XCRK. In accordance with this, the expression of resistanceand oxidation-related genes Wrky77, Wrky13, PAL1, PR5,Fe-SOD and SodCc2 were up-regulated by the overexpressionof XCRK, which might contribute collectively to the increasedXoc tolerance. Overall, overexpression of XCRK couldenhance the antioxidant capacity and Xoc tolerance in rice.
