PID Passivity-Based Control of Nonlinear Systems with Applications
by Romeo Ortega, Jose Guadalupe Romero, Pablo Borja, Alejandro Donaire
2021 · John Wiley & Sons
Explore the foundational and advanced subjects associated with proportional-integral-derivative controllers from leading authors in the field In PID Passivity-Based Control of Nonlinear Systems with Applications, expert researchers and authors Drs. Romeo Ortega, Jose Guadalupe Romero, Pablo Borja, and Alejandro Donaire deliver a comprehensive and detailed discussion of the most crucial and relevant concepts in the analysis and design of proportional-integral-derivative controllers using passivity techniques. The accomplished authors present a formal treatment of the recent research in the area and offer readers practical applications of the developed methods to physical systems, including electrical, mechanical, electromechanical, power electronics, and process control. The book offers the material with minimal mathematical background, making it relevant to a wide audience. Familiarity with the theoretical tools reported in the control systems literature is not necessary to understand the concepts contained within. You’ll learn about a wide range of concepts, including disturbance rejection via PID control, PID control of mechanical systems, and Lyapunov stability of PID controllers. Readers will also benefit from the inclusion of: A thorough introduction to a class of physical systems described in the port-Hamiltonian form and a presentation of the systematic procedures to design PID-PBC for them An exploration of the applications to electrical, electromechanical, and process control systems of Lyapunov stability of PID controllers Practical discussions of the regulation and tracking of bilinear systems via PID control and their application to power electronics and thermal process control A concise treatment of the characterization of passive outputs, incremental models, and Port Hamiltonian and Euler-Lagrange systems Perfect for senior undergraduate and graduate students studying control systems, PID Passivity-Based Control will also earn a place in the libraries of engineers who practice in this area and seek a one-stop and fully updated reference on the subject.
Antimicrobial Polymers
by Jose Maria Lagaron, Maria Jose Ocio, Amparo Lopez-Rubio
2011 · John Wiley & Sons
The pioneering guide on the design, processing, and testing of antimicrobial plastic materials and coatings The manifestation of harmful microbes in plastic materials used in medical devices and drugs, water purification systems, hospital equipment, textiles, and food packaging pose alarming health threats to consumers by exposing them to many serious infectious diseases. As a result, high demand for intensifying efforts in the R&D of antimicrobial polymers has placed heavy reliance on both academia and industry to find viable solutions for producing safer plastic materials. To assist researchers and students in this endeavor, Antimicrobial Polymers explores coupling contaminant-deterring biocides and plastics—focusing particular attention on natural biocides and the nanofabrication of biocides. Each chapter is devoted to addressing a key technology employed to impart antimicrobial behavior to polymers, including chemical modification of the polymers themselves. A host of relevant topics, such as regulatory matters, human safety, and environmental risks are covered to help lend depth to the book's vital subject matter. In addition, Antimicrobial Polymers: Discusses the design, processing, and testing of antimicrobial plastic materials Covers interdisciplinary areas of chemistry and microbiology Includes applications in food packaging, medical devices, nanotechnology, and coatings Details regulations from the U.S. (FDA and EPA) and EU as well as human safety and environmental concerns Achieving cleaner and more effective methods for improving the infection-fighting properties of versatile and necessary plastic materials is a goal that stretches across many scientific fields. Antimicrobial Polymers combines all of this information into one volume, exposing readers to preventive strategies that harbor vast potential for making exposure to polymeric products and surfaces a far less risky undertaking in the future.
Texas Association of Chicanos in Higher Education, The
by Jose Angel Gutierrez and Natalia Verjat Gutierrez
2013 · Arcadia Publishing
For the past 40 years, the Texas Association of Chicanos in Higher Education (TACHE) has been on the forefront of advocacy to improve opportunity in higher education for US persons of Mexican origin. This volume in the ongoing Images of America series chronicles the history of this unique organization.
Island biogeography is the study of the distribution and dynamics of species in island environments. Due to their isolation from more widespread continental species, islands are ideal places for unique species to evolve, but they are also places of concentrated extinction. Not surprisingly, they are widely studied by ecologists, conservationists and evolutionary biologists alike. There is no other recent textbook devoted solely to island biogeography, and a synthesis of the many recent advances is now overdue. This second edition builds on the success and reputation of the first, documenting the recent advances in this exciting field and explaining how islands have been used as natural laboratories in developing and testing ecological and evolutionary theories. In addition, the book describes the main processes of island formation, development and eventual demise, and explains the relevance of island environmental history to island biogeography. The authors demonstrate the huge significance of islands as hotspots of biodiversity, and as places from which disproportionate numbers of species have been extinguished by human action in historical time. Many island species are today threatened with extinction, and this work examines both the chief threats to their persistence and some of the mitigation measures that can be put in play with conservation strategies tailored to islands.
Presidential Primaries in Puerto Rico
by Juan Jose Nolla-Acosta, Elizabeth Silen-Afanador
2019 · Lulu.com
Puerto Rico, like all the other US Territories, has a very limited participation in the process to elect the President. Both major parties have given Puerto Rico some delegates at their national convention. This book concentrates on the experience Puerto Rico has had on the nominating processes of both parties, particularly since 1980, when it began having presidential primaries. Unfortunately, once the primary season ends, Puerto Rico, like the rest of the territories, go back to be totally ignored by the presidential candidates. That's because the American citizens who live in Puerto Rico and the territories don't count at all in the general election. This unfair situation must change. The solution for this problem, in the case of Puerto Rico, is full admission into the union as a state. Puerto Rico has already voted twice in favor of becoming a state, in 2012 and 2017. It's time for Congress to act and grant the US citizens the political equality they have voted for.
