Adaptive stabilization for ODE systems coupled with parabolic PDES

This paper is concerned with the adaptive stabilization for ODE systems coupled with parabolic PDEs. The presence of the uncertainties/unknonws and the coupling between the subsystems makes the system under investigation essentially different from those of the existing literature, and hence induces more technique obstacles in control design. Motivated by the related literature, an invertible infinite-dimensional backstepping transformation with appropriate kernel functions is first introduced to change the original system into a new one, from which the control design becomes much convenient. It is worthwhile pointing out that, since the kernel equations for which the kernel functions satisfy are coupled rather than cascaded, the desirable kernel functions are more difficult to derive than those of the closely related literature. Then, by Lyapunov method and a dynamics compensated technique, an adaptive stabilizing controller is successfully constructed, which guarantees that all the closed-loop system states are bounded while the original system states converging to zero. Finally, a simulation example is provided to validate the proposed method.     

Educational systems design: Making it more user friendly

Concerns about our current public education systems have given rise to a variety of reform efforts. During the past several years, efforts have begun to emphasize the importance of systems thinking and a “systemic” approach for bringing about fundamental educational reform. In spite of the promise of system design as a model for systemic change, it has been largely ignored by its intended clients, the educational leadership. This paper explores some of the reasons for this and proposes a number of actions that need to be taken if system design is to become a viable approach.

Analyzing Collaboration as Drama

The need for inter- and intraorganizational collaboration is ubiquitous. People, groups, and organizations work together at all levels to achieve their ends, sometimes (as in a supply chain) for mutual benefit, at others (as in wage negotiations) to satisfy conflicting needs. Viewing these interactions through the metaphor, not of games but of drama, has led to fresh insights. This paper outlines the analytical theory of drama which has been developed and shows how it can be applied to practical situations. The theory, which can be expressed tightly in the mathematics of set theory, demonstrates how six specific tendencies for a situation to change from the impasse which is arrived at through participants' unresolved differences generates distinctive transformations that lead to a new (and possibly resolvable) situation. It thus moves beyond classical game theory by describing games which change under the internal pressures which they contain.     

Two kinds of harmonic problems in control systems

This paper discusses the harmonic problems in control systems from two aspects: One is the harmonic control among different subsystems, and the other is the harmonic control among multiple inputs. Some intrinsic problems in such systems are discussed. It is pointed out that some subsystems must be unstable to stabilize the whole interconnected system by an example. Especially for discrete-time multi-input systems, a necessary and sufficient condition is presented for the strict decrease of the quadratic optimal performance index with the control input extensions. This shows an essential difference between single-input and multi-input control systems. Finally, some future research directions are discussed in harmonic control of interconnected systems, allocation of multi-control inputs, fault-tolerant control, and fault-diagnosis.

必须用系统协调的观点和方法构建和谐社会

社会系统是由相互联系、相互作用和相互制约的各子系统组成的一个有机整体。和谐社会要求社会系统中的经济子系统、政治子系统、文化意识子系统相互协调、相互适应、相互一致。在市场经济条件下,经济体制改革需要政治体制改革相配套,否则社会子系统之间就会不平衡,和谐社会就难以实现。     

New multi-DSP parallel computing architecture for real-time image processing

1. INTRODUCTION The usually designing process of image processing system is first to select reasonable algorithm according to the case-to-case requirement of application, and then decide the hardware architecture based on the algorithm. However, it is not a good choice because of the diversity of image processing algorithms. So it is necessary to develop a general reconfigurable and expandable multi-DSP real-time image processing system[1-5]. On the one hand, the system must have powerfu…

论系统思维(六):重在把握系统的整体涌现性

系统思维反对笼统地谈论整体，认定具有涌现性的事物才是系统。涌现并不神秘，它来自系统组分之间、系统与环境之间的相互作用，是对事物进行组织的产物。涌现带来的不是物质能量的增减，而是信息的创生与消除。系统思维就是按照涌现论识物想事的思维方式。

The routing and cost of the information flow in a system

A study of information flows in different types of procedures used for the management of the agricultural credit in the Agricultural Bank of Greece is discussed in this paper. Systems and subsystems are structured using new diagrammatical notation in order to identify explicitly the system. The communication network of the information flow with certain nodes (individuals) and types of links (types of communication) is also considered. In addition to the normal link cost of such diagrams, a node cost, which depends on the types of links involved in the network, is included. An optimal routing from a given node to its destination node can thus be sought. The conditions of stability and change of the system are examined from the information flow cost point of view through the procedures associated with short-term agricultural loans.     

基于焦元距离的冲突证据组合规则

由于Dempster-Shafer理论(Dempster-Shafer theory, DST)组合规则归一化计算导致冲突信息的不合理分配,使得处理高冲突证据时常常得到违背直觉的合成结果,因此在很大程度上制约了它的应用。提出了一种基于焦元距离的冲突证据组合规则,首先通过定义焦元距离的概念来获得证据源的权重因子,并引入了焦元置信指派的数学期望和方差关系来定义证据焦元的信任度和相似度,通过分析局部冲突产生的原因,利用冲突焦元提供的信息将冲突信息进行局部分配。实验结果表明,新的组合规则不但可以有效地解决高冲突证据融合问题,而且在最差的融合顺序下也能得到合理的融合结果。
