"This versatile book teaches control system design using H∞infty techniques that are simple and compatible with classical control, yet powerful enough to quickly allow the solution of physically meaningful problems. The authors begin by teaching how to formulate control system design problems as mathematical optimization problems and then discuss the theory and numerics for these optimization problems. Their approach is simple and direct, and since the book is modular, the parts on theory can be read independently of the design parts and vice versa, allowing readers to enjoy the book on many levels.The development of H∞infty engineering was one of the main accomplishments of control in the 1980s. However, until now, there has not been a publication suitable for teaching the topic at the undergraduate level. This book fills that gap by teaching control system design using H∞infty techniques at a level within reach of the typical engineering and mathematics student. It also contains a readable account of recent developments and mathematical connections.The authors treat control design problems in a physically correct way. They present a small set of specific rules that the reader can apply to convert a particular design problem to the fundamental optimization problem of H∞infty control. This precisely formulated mathematics problem can then be solved on a computer. The book introduces the control software package OPTDesign, which allows the reader to easily reproduce the calculations done in the solved examples and even try variations on them. The description of how to convert an engineering problem to a form suitable for CAD is simpler than in other books."

"One of the main accomplishments of control in the 1980s was the development of H∞ techniques. This book teaches control system design using H∞ methods. Students will find this book easy to use because it is conceptually simple. They will find it useful because of the widespread appeal of classical frequency domain methods.Classical control has always been presented as trial and error applied to specific cases; Helton and Merino provide a much more precise approach. This has the tremendous advantage of converting an engineering problem to one that can be put directly into a mathematical optimization package.After completing this course, students will be familiar with how engineering specs are coded as precise mathematical constraints."

"This book investigates the problem of non-fragile H-infinity filter design for Takagi-Sugeno (T-S) fuzzy systems. Given a T-S fuzzy system, the objective of this book is to design an H-infinity filter with the gain variations such that the filtering error system guarantees a prescribed H-infinity performance level. Furthermore, it demonstrates that the solution of non-fragile H-infinity filter design problem can be obtained by solving a set of linear matrix inequalities (LMIs). "

"H∞ control originated from an effort to codify classical control methods, where one shapes frequency response functions for linear systems to meet certain objectives. H∞ control underwent tremendous development in the 1980s and made considerable strides toward systematizing classical control. This book addresses the next major issue of how this extends to nonlinear systems.At the core of nonlinear control theory lie two partial differential equations (PDEs). One is a first-order evolution equation called the information state equation, which constitutes the dynamics of the controller. One can view this equation as a nonlinear dynamical system. Much of this volume is concerned with basic properties of this system, such as the nature of trajectories, stability, and, most important, how it leads to a general solution of the nonlinear H∞ control problem.The second PDE actually builds on a classical type of partial differential inequality (PDI) called a Bellman-Isaacs inequality. While the information state PDE determines the dynamics of the controller, the PDI determines the output of the controller. The authors explore the system theoretic significance of the PDI and present its gross structure. These equations are only a few years old and their study is an expanding area of research.This book also emphasizes the theory effecting computer solvability of the information state equation, which at the outset looks numerically intractable, but which surprisingly is in many cases tractable. For example, the theory shows that careful initialization has a major influence on computer solvability.The authors keep the book self-contained by using the appendices to help explain certain prerequisite material. The reader should have a basic knowledge of control theory, real analysis and differential equations, nonlinear operator theory, and nonlinear PDEs."

"This monograph presents a unified mathematical framework for a wide range of problems in estimation and control. The authors discuss the two most commonly used methodologies: the stochastic H2 approach and the deterministic (worst-case) H� approach. Despite the fundamental differences in the philosophies of these two approaches, the authors have discovered that, if indefinite metric spaces are considered, they can be treated in the same way and are essentially the same."

"ABSTRAKPenelitian ini bertujuan untuk mengetahui bagaimana elemen-elemen movie marketing mix dalam suatu film Avengers: Infinity War people, feature, script, price, promotion, dan distribution) dan frekuensi kehadiran dalam kegiatan seni atau budaya (attendance) dapat mempengaruhi keinginan penonton untuk menonton film tersebut dan melakukan electronic word of mouth. Selain itu penelitian ini juga ingin mengetahui apakah karakter kepribadian extraversion mempengaruhi seseorang dalam melakukan electronic word of mouth. Pengolahan data dilakukan menggunakan metode Structural Equation Modeling (SEM). Hasil penelitian menunjukan bahwa variabel people dan script memiliki pengaruh positif terhadap purchase intention. Frekuensi attendance tidak berpengaruh terhadap purchase intention. Selanjutnya purchase intention dan karakter kepribadian extraversion berpengaruh secara positif terhadap electronic word of mouth.

ABSTRACTThis study aims to find out how the elements of movie marketing mix in Avengers: Infinity War movie (people, feature, script, price, promotion, and distribution) can affect the audiences intention to watch movies (purchase intention), as well as the impact of their intention to watch movies (purchase intention) on electronic word of mouth (EWOM). In addition, this study also wants to find out whether the frequency of attendance in art or cultural activities (attendance) can affect the audiences intention to watch movies (purchase intention) and dimension between elements of movie marketing mix and purchase intention. The character of extraversion personality traits was also tested for its effect on electronic word of mouth (EWOM). This research was conducted on one specific movie object, which is Avengers: Infinity War. Data processing is done by using Structural Equation Modeling (SEM). The results showed that people and script have a positive effect to purchase intention. Attendance does not have effect to purchase intention. Furthermore, purchase intention and extraversion personality traits have positive effect to electronic word of mouth."

"Problem kuasa simbolik seringkali kita temukan dalam relasi antar-individu. Hal ini mengakibatkan keunikan tiap-tiap individu tereliminasi dalam relasi tersebut. Hal ini dikarenakan oleh adanya pemahaman kita yang tidak jernih tentang cinta. Pemikiran Alain Badiou berusaha menggagas suatu konsep cinta yang jernih yang mengutamakan pluralitas dalam suatu relasi antar-individu. Gagasan tersebut didasarkan pada ontologi tentang multiplisitas yang multiple. Dengan konsepsi cinta ini relasi tersebut akan mewujudkan otonomi tiap-tiap individu yang terlibat, sehingga problem kuasa simbolik dapat teratasi.

Problem of symbolic power often we found in inter-individual relations. This causes the uniqueness of every individual is eliminated in the relation. This is because of our unclear understanding about love. Alain Badiou's thought attempts to conceptualize a clear conception of love that give priority to plurality in an inter-individual relation. This concept is based on the ontology of multiple multiplicities. With this conception of love, the relation will construct the autonomy of every individual who is involved, so that the problem of symbolic power can be solved."
