Process Control - The Passive Systems Approach (Advances In Industrial Control)(Springer, 2007)

ISBN 9781846288920

Process Control introduces an emerging area in process control – control system analysis and design based on the concept of passive systems. Passive systems are a class of processes that dissipate certain types of physical or virtual energy, defined by Lyapunov-like functions. Passivity and associated stability conditions form one of the cornerstones in control theory and have recently begun to be applied in process control. Defined as an input-output property, the concept of passivity implies stability conditions for interconnected systems. Passive systems are minimum phase and thus very easy to control via output feedback, even if they are highly nonlinear and coupled. Therefore, the passivity framework can be used in process input-output controllability analysis as well as control design. Here, the concept of passive systems is also linked to process thermodynamics to provide process engineers with insights into the physical bases of the above results.

In this book, passivity-based developments in the areas of robust process control, decentralized control, fault tolerant control, process controllability analysis and nonlinear process control are addressed systematically for the first time. Written for the industrial, engineering and academic communities, the emphasis is placed on results that enhance insight and intuition.
