Actuator and sensor delays are among the most common dynamic phenomena in engineering practice, and when disregarded, they render controlled systems unstable. Over the past sixty years, predictor feedback has been a key tool for compensating such delays, but conventional predictor feedback algorithms assume that the delays and other parameters of a given system are known. When incorrect parameter values are used in the predictor, the resulting controller may be as destabilizing as without the delay compensation.Delay-Adaptive Linear Control develops adaptive predictor feedback algorithms equipped with online estimators of unknown delays and other parameters. Such estimators are designed as nonlinear differential equations, which dynamically adjust the parameters of the predictor. The design and analysis of the adaptive predictors involves a Lyapunov stability study of systems whose dimension is infinite, because of the delays, and nonlinear, because of the parameter estimators. This comprehensive book solves adaptive delay compensation problems for systems with single and multiple inputs/outputs, unknown and distinct delays in different input channels, unknown delay kernels, unknown plant parameters, unmeasurable finite-dimensional plant states, and unmeasurable infinite-dimensional actuator states.Presenting breakthroughs in adaptive control and control of delay systems, Delay-Adaptive Linear Control offers powerful new tools for the control engineer and the mathematician.

Although one of the oldest microbial technologies used in food processing, solid-state fermentation (SSF) had, until recently, fallen out of favor. However, based on a series of established mathematical models, new design concepts for SSF bioreactors and process control strategies have been proposed, allowing SSF technology to reach new levels. Solid State Fermentation for Foods and Beverages covers these new technologies and their application to food and beverage production. The book systematically describes the production of solid-state fermented food and beverage in terms of the history and development of SSF technology and SSF foods, bio-reactor design, fermentation process, various substrate origins and sustainable development. It emphasizes Oriental traditional foods produced by SSF such as sufu, vinegar, soy sauce, Chinese distilled spirit, and rice wine. The authors address such engineering issues as mass and heat transfer and energy equation calculation of solid-state fermentation, dynamic modeling of solid-state fermentation, and process control of solid-state fermentation. Covering the latest developments and achievements in the field of SSF, the book provides a detailed introduction to various solid-state fermented foods and beverages, including product category, characteristics, functionalities, safety issues, and consumer perception. It explores real advantages of SSF processes and how their application at real scale for high quality production that is more and less costly.

"Functional carbohydrates" is the term used to describe those carbohydrates that play an important role in strengthening immunity, decreasing the level of blood-lipid, and regulating the intestinal flora of humans, beyond those simply used as the energy-supplying materials. To date functional carbohydrates mainly cover dietary fiber, functional polysaccharides, functional oligosaccharides, sugar alcohols, and other functional monosaccharides. Functional Carbohydrates: Development, Characterization, and Biomanufacture facilitates tracking the important progresses in functional carbohydrates. This book addresses the history and recent developments of a selected number of important functional carbohydrates and it introduces the source, properties, and applications of a number of functional carbohydrates. It describes in detail the biomanufacture of these carbohydrates based on fermentation or enzyme catalysis, including the strain screening and improvement, optimization of fermentation process, and product downstream processing.
