Asynchronous Control for Positive Markov Jump Systems
Kai Yin,Dedong Yang,Jiao Liu,Hongchao Li 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.2
A new result is provided for the asynchronous control analysis of positive Markov jump systems (PMJSs) in this paper. Firstly, a hidden Markov model is described to express the asynchronous circumstances that appear between the system modes and controller modes. Secondly, by utilizing a copositive stochastic Lyapunov function, a sufficient and necessary condition is given to guarantee the mean stability of PMJSs. Thirdly, we obtain another equivalent condition and design the corresponding asynchronous controller. Finally, the correctness of these results is verified by two numerical examples.

Plant Bowman-Birk type bran trypsin inhibitors(BBTI) belong to a family of serine protease inhibitors thatinhibit trypsin activity and play roles in plant developmentand defense responses to both biotic and abiotic stresses. Inthis study, transgenic rice plants overexpressing BBTI4 (OXBBTI4)were generated. Reverse-transcription polymerasechain reaction and western blot (WB) analysis demonstratedthat the BBTI4 mRNA and protein levels were significantlyincreased in OX-BBTI4. Notably, two BBTI4 protein formswith different molecular weight (18 kD and 28 kD) wererevealed by WB analysis. In non-transgenic plants, BBTI4-28kD and BBTI4-18kD were mainly expressed in roots andleaves, respectively, while in transgenic OX-BBTI4 plants,both protein forms were expressed constitutively. Subcellularanalysis revealed that BBTI4 is localized in the cytosol. Moreover, Xanthomonas oryzae pv. oryzae (Xoo) inoculationexperiments demonstrated that transgenic OX-BBTI4 riceplants conferred partial but broad-spectrum Xoo resistance. InOX-BBTI4 transgenic rice plants, the expression of OsPR3 andOsPR10a proteins was induced and gradually increased afterXoo infection, while the expression of OsPR1a, OsPR1b andOsPR-pha remained unchanged. Taken together, these resultssuggest that BBTI4 may play a role in rice resistance to Xoo,and OsPR3 and OsPR10a may be involved in the OX-BBTI4-dependent partial Xoo resistance response.
