推广物联网应用提升信息化水平

物联网被称为继计算机、互联网之后世界信息产业的第三次浪潮。美国更是把发展以物联网为基础的“智慧地球”作为美国迅速走出金融危机,重现经济繁荣与发展的希望所在。2009年8月7日,温家宝总理在无锡新区考察微纳传感网工程技术研发中心时指出,从信息处理到信息传播再到信息传感,信息发展越来越进入物质领域。     

浅谈物联网建设中的几个关键问题

2010年3月5日,温家宝总理在政府工作报告中提出了加快物联网建设。物联网作为新兴战略性产业,其发展必将对我国未来经济与社会发展产生深远影响。     

物联网初探

温家宝总理于2009年8月在江苏无锡考察物联网产业发展时明确指示：“尽快建立中国的传感信息中心,或者叫‘感知中国’中心。要早一点谋划未来,早一点攻破核心技术,要依靠科技和人才,占领科技和经济发展制高点,保证我国具有可持续发展的能力和可持续的竞争力。”为落实温总理的指示,     

三网融合与移动收购腾讯

三网融合目前已经是千真万确大势所趋的事情了。在年初,国务院总理温家宝主持召开的国务院常务会议上,就已经做出决定,要加快推进电信网、广播电视网和互联网三网融合。温总理还在会议上指出,目前我国已基本具备进一步开展三网融合的技术条件、网络基础和市场空间,加快推进三网融合已进入关键时期。会议提出了推进三网融合的阶段性目标。     

Stability and control of nonlinear systems described by retarded functional equations: a review of recent results

This paper reports on recent results in a series of the work of the authors on the stability and nonlinear control for general dynamical systems described by retarded functional differential and difference equations. Both internal and external stability properties are studied. The corresponding Lyapunov and Razuminkhin characterizations for input-to-state and input-to-output stabilities are proposed. Necessary and sufficient Lyapunov-like conditions are derived for robust nonlinear stabilization. In particular, an explicit controller design procedure is developed for a new class of nonlinear time-delay systems. Lastly, sufficient assumptions, including a small-gain condition, are presented for guaranteeing the input-to-output stability of coupled systems comprised of retarded functional differential and difference equations.     

Lyapunov-based boundary feedback control in multi-reach canals

This paper presents a Lyapunov-based approach to design the boundary feedback control for an openchannel network composed of a cascade of multi-reach canals, each described by a pair of Saint-Venant equations. The weighted sum of entropies of the multi-reaches is adopted to construct the Lyapunov function. The time derivative of the Lyapunov function is expressed by the water depth variations at the gate boundaries, based on which a class of boundary feedback controllers is presented to guarantee the local asymptotic closed-loop stability. The advantage of this approach is that only the water level depths at the gate boundaries are measured as the feedback.
