Observer-based decentralized control of large-scale stochastic high-order feedforward systems with multi time delays     

Liang Liu  Shengyuan Xu  Xue-Jun Xie  Bing Xiao 《Journal of The Franklin Institute》2019,356(16):9627-9645

This paper investigates the problem of observer-based decentralized control for a class of large-scale stochastic high-order feedforward systems with multi time delays. By using the homogeneous domination idea and constructing the implementable observer, the decentralized output-feedback controller design scheme is firstly proposed. Then, with the aid of stochastic time delay system stability theory, the globally asymptotically stable in probability of the closed-loop system is verified by selecting an appropriate Lyapunov–Krasoviskii functional. Finally, an example is provided to demonstrate the efficiency of the proposed design method.  相似文献   

Dynamics of student interactions: an empirical study of orienteering lessons in physical education     

Clément Jourand  David Adé  Carole Sève  John Komar  Régis Thouvarecq 《Physical Education & Sport Pedagogy》2018,23(2):134-149

Introduction: Many studies in physical education (PE) have sought to identify and categorize the modes of student interaction in order to gain greater insight into the nature of cooperative activity. More others recent studies have examined how modes of interaction evolve on the basis of the modes of collective activity that they generate. These studies have shown to describe and explain the interactions among individuals and the processes they generate, which then lead to the construction, deconstruction or reconstruction of different interaction modes. Although some studies have sought to describe the dynamics of student interactions, very few have quantified these dynamics. By doing so, however, researchers might gain a new perspective on student interaction modes that inspires new designs for teaching in PE, thereby having professional impact. The present study extends this research by investigating the dynamics of student interaction, with a focus on the emergence of interaction modes during orienteering lessons. For this purpose, the study was conducted within the methodological framework of course of action theory, which is an effective approach for examining activity in natural situations to provide insight into the experience of activity from the actors perspective.

Method: The study was conducted in two classes of seventh-grade students (about 12 years old) in which 16 students volunteered and were available for post-action interviews immediately after the lessons under study. These volunteers were placed in eight affinity-based dyads. The teachers planned orienteering lessons at similar levels of difficulty and duration but modified the lessons across a range of contextual features. Two categories of data were collected: (1) data from audiovisual recordings as the students searched for the checkpoints and (2) verbalization data during the post-action interviews with the students. The data were processed in two steps: one qualitative, the other quantitative. The qualitative step consisted of processing the data of the student experiences to characterize their interactions in the three different contexts. In the quantitative step, the data from the first step were graphically represented to depict the interaction dynamics within the student dyads.

Results and discussion: The qualitative analysis showed the emergence of three modes of student interaction shared across each learning context: co-construction, confrontation and delegation. The quantitative analysis revealed the percentages of the different modes of interaction and therefore characterized the interaction dynamics. Our results showed that the interaction dynamics within the dyads were both unique and similar in the task contexts in terms of both ratios of change and distribution. Results are discussed across two major points of interest: (1) the observation of the same interaction modes whatever the context yet with quite different dynamics and (2) proposals for PE teacher interventions.  相似文献   

Anonymous body or first patient? A status report and needs assessment regarding the personalization of donors in dissection courses in German,Austrian, and Swiss Medical Schools          下载免费PDF全文

Friederike Hasselblatt  David A.C. Messerer  Oliver Keis  Tobias M. Böckers  Anja Böckers 《Anatomical sciences education》2018,11(3):282-293

Many Anglo‐American universities have undertaken a paradigm shift in how the dissection of human material is approached, such that students are encouraged to learn about the lives of body donors, and to respectfully “personalize” them as human beings, rather than treating the specimens as anonymous cadavers. For the purposes of this study, this provision of limited personal information regarding the life of a body donor will be referred to as “personalization” of body donors. At this time, it is unknown whether this paradigm shift in the personalization of body donors can be translated into the German‐speaking world. A shift from donor anonymity to donor personalization could strengthen students' perception of the donor as a “first patient,” and thereby reinforce their ability to empathize with their future patients. Therefore, this study aimed to collect data about the current status of donation practices at German‐speaking anatomy departments (n = 44) and to describe the opinions of anatomy departments, students (n = 366), and donors (n = 227) about possible donor personalization in medical education. Anatomy departments in Germany, Austria, and Switzerland were invited to participate in an online questionnaire. One‐tenth of registered donors at Ulm University were randomly selected and received a questionnaire (20 items, yes‐no questions) by mail. Students at the University of Ulm were also surveyed at the end of the dissection course (31 items, six‐point Likert‐scale). The majority of students were interested in receiving additional information about their donors (78.1%). A majority of donors also supported the anonymous disclosure of information about their medical history (92.5%). However, this information is only available in about 28% of the departments surveyed and is communicated to the students only irregularly. Overall, 78% of anatomy departments were not in favor of undertaking donor personalization. The results appear to reflect traditional attitudes among anatomy departments. However, since students clearly preferred receiving additional donor information, and most donors expressed a willingness to provide this information, one could argue that a change in attitudes is necessary. To do so, official recommendations for a limited, anonymous personalization of donated cadaveric specimens might be necessary.

Synergetic governing controller design for the hydraulic turbine governing system with complex conduit system     

Jianzhong Zhou  Yuncheng Zhang  Yang Zheng  Yanhe Xu 《Journal of The Franklin Institute》2018,355(10):4131-4146

The hydraulic turbine governing system plays an indispensable role in maintaining the stability of electrical power system. In this paper, synergetic control theory is introduced to enhance the regulating ability of the hydraulic turbine governing system. For the purpose of describing the characteristics of objective system and deducing the synergetic control rule, a nonlinear mathematic model of a hydraulic turbine governing system with long tail race and two surge tanks is established. Furthermore, the nonlinear characteristic of the hydraulic turbine is described by six variable partial derivatives. For further investigation, the hydraulic turbine governing system is conducted to running under load condition when its coaxial generator connects to an infinite bus. Simulation experiments have been made under both load disturbance and three-phase short circuit fault conditions to compare the dynamic performances of proposed synergetic governing controller and classic PID controller. The results indicate that the proposed synergetic governing controller is an effective alternative in normal condition and a superior one in emergency. Moreover, the robustness of synergetic governing controller has also been discussed at the end of this paper.  相似文献   

New insights in stability analysis of delayed Lotka–Volterra systems     

Xu-Guang Li  Jun-Xiu Chen  Silviu-Iulian Niculescu  Arben Çela 《Journal of The Franklin Institute》2018,355(17):8683-8697

Most of the reported Lotka–Volterra examples have at most one stability interval for the delay parameters. Furthermore, the existing methods fall short in treating more general case studies. Inspired by some recent results for analyzing the stability of time-delay systems, this paper focuses on a deeper characterization of the stability of Lotka–Volterra systems w.r.t. the delay parameters. More precisely, we will introduce the recently-proposed frequency-sweeping approach to study the complete stability problem for a broad class of linearized Lotka–Volterra systems. As a result, the whole stability delay-set can be analytically determined. Moreover, as a significant byproduct of the proposed approach, some Lotka–Volterra examples are found to have multiple stability delay-intervals. To the best of the authors’ knowledge, such a characterization represents a novelty for having some insights in the population dynamics: in some situations, a longer maturation period of species is helpful for the stability of a population system.  相似文献
