Enhanced State Feedback Control of T-S Fuzzy Systems with Time-delays

Abstract: In this paper, the issue of designing an enhanced controller is exploited for time-delayed nonlinear systems on the basis of T-S fuzzy models. At present, a large number of existing design methods of fuzzy controller independent on membership functions, which are doubtlessly conservative. To overcome the aforementioned shortage, this paper first establishes a novel Lyapunov-Krasovskii functional containing both delay-product-type terms and membership functions. Then, a membership-function-dependent stability criterion is developed by using Wirtinger-based integral inequality and an extended reciprocally convex matrix inequality. Subsequently, an improved state feedback fuzzy controller is designed. Finally, the merits and the availability of the obtained stability criterion and fuzzy controller designed method are verified by two numerical examples.

Energy Saving Control Strategies: Motor-Driven Active Suspension

Abstract: One of the disadvantages of the active suspension is its high energy consumption, which limits its application. To overcome this problem, in recent years, researchers pay much attention to reducing energy consumption of active suspensions to make active suspensions widely used, and there are many remarkable results. A great deal of energy is dissipated in the form of heat through the viscous damper and the actuator. In other words, most of the vibration energy excited by road is transferred into useless heat energy. If we can recycle vibration energy excited by the uneven road in some way, it is attainable to consume less energy, even to achieve a self-powered suspension. So energy saving control strategies of active suspensions is a research field worth studying.

Command Filtered Adaptive Fuzzy Backstepping FTC Against Actuator Fault

Abstract: This chapter investigates the problem of fuzzy adaptive tracking control for a class of uncertain nonlinear strict-feedback systems with actuator fault. The actuator fault is assumed to have not only time-varying gain fault but also time-varying bias fault. Combining command filtered backstepping design with the integral-type Lyapunov function and utilizing Nussbaum-type gain technique, an adaptive fuzzy fault-tolerant control scheme is proposed to guarantee that the resulting closed-loop system is asymptotically bounded with the tracking error converging to a neighborhood of the origin. The control scheme requires only virtual control and its first one derivative instead of them and their higher derivatives in backstepping design procedures. Simulation results demonstrate the effectiveness of the proposed techniques.

Robust Output Synchronization via Internal Model Principle

Abstract: Recently, the synchronization problem of LSNSs has attracted considerable attention in systems and control community, due to its application to a wide range of problems, including sensor networks, rendezvous, formation control and flocking control [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]. The agents exchange information through a communication graph, which is a time-varying graph [13, 14, 15, 16] or a time-invariant graph [17, 18, 19, 20]. The dynamics of individual agents in the network can be identical.

I and i

Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

The Oxford Handbook of Innovation

Abstract: This handbook looks to provide academics and students with a comprehensive and holistic understanding of the phenomenon of innovation. Innovation spans a number of fields within the social sciences and humanities: Management, Economics, Geography, Sociology, Politics, Psychology, and History. Consequently, the rapidly increasing body of literature on innovation is characterized by a multitude of perspectives based on, or cutting across, existing disciplines and specializations. Scholars of innovation can come from such diverse starting points that much of this literature can be missed, and so constructive dialogues missed. The editors of The Oxford Handbook of Innovation have carefully selected and designed twenty-one contributions from leading academic experts within their particular field, each focusing on a specific aspect of innovation. These have been organized into four main sections, the first of which looks at the creation of innovations, with particular focus on firms and networks. Section Two provides an account of the wider systematic setting influencing innovation and the role of institutions and organizations in this context. Section Three explores some of the diversity in the working of innovation over time and across different sectors of the economy, and Section Four focuses on the consequences of innovation with respect to economic growth, international competitiveness, and employment. An introductory overview, concluding remarks, and guide to further reading for each chapter, make this handbook a key introduction and vital reference work for researchers, academics, and advanced students of innovation.

Fundamentals of Queueing Theory

Abstract: Praise for the Third Edition: "This is one of the best books available. Its excellent organizational structure allows quick reference to specific models and its clear presentation . . . solidifies the understanding of the concepts being presented."IIE Transactions on Operations EngineeringThoroughly revised and expanded to reflect the latest developments in the field, Fundamentals of Queueing Theory, Fourth Edition continues to present the basic statistical principles that are necessary to analyze the probabilistic nature of queues. Rather than presenting a narrow focus on the subject, this update illustrates the wide-reaching, fundamental concepts in queueing theory and its applications to diverse areas such as computer science, engineering, business, and operations research.This update takes a numerical approach to understanding and making probable estimations relating to queues, with a comprehensive outline of simple and more advanced queueing models. Newly featured topics of the Fourth Edition include:Retrial queuesApproximations for queueing networksNumerical inversion of transformsDetermining the appropriate number of servers to balance quality and cost of serviceEach chapter provides a self-contained presentation of key concepts and formulae, allowing readers to work with each section independently, while a summary table at the end of the book outlines the types of queues that have been discussed and their results. In addition, two new appendices have been added, discussing transforms and generating functions as well as the fundamentals of differential and difference equations. New examples are now included along with problems that incorporate QtsPlus software, which is freely available via the book's related Web site.With its accessible style and wealth of real-world examples, Fundamentals of Queueing Theory, Fourth Edition is an ideal book for courses on queueing theory at the upper-undergraduate and graduate levels. It is also a valuable resource for researchers and practitioners who analyze congestion in the fields of telecommunications, transportation, aviation, and management science.
