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.

"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.
