Networked H∞ filtering for Takagi–Sugeno fuzzy systems under multi-output multi-rate sampling

This paper studies networked H_∞ filtering for Takagi–Sugeno fuzzy systems with multi-output multi-sensor asynchronous sampling. Different output variables in a dynamic system are sampled by multiple sensors with different sampling rates. To estimate the signals of such a system, a continuous multi-rate sampled-data fusion method is proposed to design a novel networked filter. By considering a class of decentralized event-triggered transmission schemes, multi-channel network-induced delays, and the updating modes of the MOMR sampled-data, a networked jumping fuzzy filter is proposed to estimate system signals based on the transmitted multi-rate sampled-data of fuzzy system and the multi-rate sampled states of filter, and the jumping among filter modes is governed by a Markov process which depends on the arrival times of sampled output sub-vectors. To deal with asynchronous membership functions, the networked fuzzy filtering system is modeled as an uncertain fuzzy stochastic system with membership function deviation bounds. Based on stability and H_∞ performance analysis, several membership-function-dependent conditions are presented to co-design the event-triggered transmission schemes and the fuzzy filter such that the filtering error system is robustly mean-square exponentially stable with a prescribed H_∞ attenuation level. Finally, the improvement in estimation performance and comparison with the existing filtering methods are discussed through simulation examples.  相似文献   

Less than expected—The minor role of foreign firms in upgrading domestic suppliers—The case of Vietnam     

Thi Xuan Thu Nguyen  Javier Revilla Diez 《Research Policy》2019,48(6):1573-1585

Vietnam is an important case for studying the impact of foreign firms’ backward linkages on local firms’ productivity. As an emerging economy Vietnam became the second most popular FDI destination after China in Pacific Asia since 2014. Our empirical analysis for Vietnam as a whole demonstrates a significant difference in the productivity growth between domestic suppliers who have a direct linkage with foreign firms and non-suppliers. This is also true for the Southeast Region (SE) with Ho-Chi-Minh City as economic center. However, in the Red River Delta (RRD), that difference is not statistically significant. Based on in-depth interviews with domestic suppliers, we reveal that in the RRD, effects of foreign firms on the productivity upgrading of domestic suppliers are indirect and limited while internal factors like absorptive capacity are more important for the productivity growth. These regional differences can be traced back to different regional specializations which still persist from the pre-reform era.  相似文献

马克思分工理论视角下的科学发展观     

刘笑菊 《湖南第一师范学报》2007,7(3):80-82

改革开放以来,随着中国经济的飞速发展,传统发展观凸显了它固有的局限性,我们党在对社会主义现代化建设规律认识不断深化的基础上,在2003年10月中共中央十六届三中全会上完整地提出了"科学发展观"。科学发展观与马克思分工理论密不可分,具有内在的一致性。马克思从科学的实践的观点出发,阐述了分工与生产力、生产关系、资源、环境等的相互关系,有助于我们今天更好地贯彻实施科学发展观。  相似文献   

Influences of Chinese educational journals—research based on 2000–2004 CSSCI     

Fang Gong  Juan Xu  Jian Fu  Sanhong Deng  Yun Bai 《Frontiers of Education in China》2007,2(4):545-567

Based on the analyses on the quality of educational periodicals and the number of publications and citations in Chinese Social Sciences Citation Index (CSSCI), this paper intends to make an analysis and introduction of the general situation of Chinese educational journals and publications during 2000–2004. Results show that the quantity of educational periodicals and papers published in China, their influence, “impact factor” and the quantity of language varieties and quotation types are not completely compatible. __________ Translated from Jiaoyu Yanjiu 教育研究 (Educational Research), 2006, (9): 8–18  相似文献   

《海洋科学》零被引论文分析     

谭雪静 《编辑学报》2017,29(1):93-95

为提高期刊质量与影响力,在中国知网中检索了《海洋科学》1994-2013年发表的论文作为研究的源数据,从刊文量及零被引率的变化、零被引论文外审专家评审意见、基金论文零被引等3个方面对零被引论文做统计和研究.认为加强选题策划、加强审稿工作、加大退稿率、不发“人情稿”,即可避免零被引,从而提升期刊的影响力.  相似文献
