The series Advances in Industrial Control aims to report and encourage technology transfer in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. New theory, new controllers, actuators, sensors, new industrial processes, computer methods, new applications, new philosophies. . . , new challenges. Much of this development work resides in industrial reports, feasibility study papers and the reports of advanced collaborative projects. The series offers an opportunity for researchers to present an extended exposition of such new work in all aspects of industrial control for widerand rapid dissemination. Benchmarking is a technique first applied by Rank Xerox in the late 1970s for business processes. As a subject in the commercial arena, benchmarking thrives with, for example, a European Benchmarking Forum. It has taken rather longer for benchmarking to make the transfer to the technical domain and even now the subject is making a slow headway. Akey research step in this direction was taken by Harris (1989) who used minimum variance control as a benchmark for controller loop assessment. This contribution opened up the area and a significant specialist literature has now developed. Significant support for the methodologywas given by Honeywell who have controller assessment routines in their process control applications software; therefore, it is timely to welcome a (first) monograph on controller performance assessment by Biao Huang and Sirish Shah to the Advances in Industrial Control series.

Controller Performance Monitoring involves the following three routine activities: (1) monitor the performance of each loop, (2) isolate poorly performing loops and (3) diagnose the cause of poor performance. A typical processing industry installs several hundreds of control loops to achieve the desired process performance. Recent studies reveal that only about one-third of controllers provide acceptable performance, indicating significant commercial benenfits exist in diagnosing and improving the remaining two thirds of the control loops. Recent surveys indicate that 20% to 30% of all control loops oscillate due to valve problems caused by static friction (also referred as stiction). Two different techniques for diagnosing stiction using routine operating data have been proposed. The success of these approaches is built on a new technique that detects and characterizes oscillations in control loops. An integrated solution strategy to compensate stiction is provided. Stiction detection and diagnosis techniques are validated on a large industrial data set.

Modeling and Control of Batch Processes presents state-of-the-art techniques ranging from mechanistic to data-driven models. These methods are specifically tailored to handle issues pertinent to batch processes, such as nonlinear dynamics and lack of online quality measurements. In particular, the book proposes: a novel batch control design with well characterized feasibility properties; a modeling approach that unites multi-model and partial least squares techniques; a generalization of the subspace identification approach for batch processes; and applications to several detailed case studies, ranging from a complex simulation test bed to industrial data. The book’s proposed methodology employs statistical tools, such as partial least squares and subspace identification, and couples them with notions from state-space-based models to provide solutions to the quality control problem for batch processes. Practical implementation issues are discussed to help readers understand the application of the methods in greater depth. The book includes numerous comments and remarks providing insight and fundamental understanding into the modeling and control of batch processes. Modeling and Control of Batch Processes includes many detailed examples of industrial relevance that can be tailored by process control engineers or researchers to a specific application. The book is also of interest to graduate students studying control systems, as it contains new research topics and references to significant recent work. Advances in Industrial Control reports and encourages the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.

This revision of the 1990 work by Thomas Fisher covers an introduction to batch processes; batch control system structures; batch control; batch communications and batch control system design. Hawkins offers a comprehensive analysis of the development and evolution of batch control from the original NAMUR model through the most current publications in the 88 series. Through examples, commentary, analogies and at times wry humor the author provides an in-depth philosophical discussion of how batch control and all manufacturing enterprises have been impacted by the work of 88. Hawkins in-depth coverage and practical insights make this book an indispensable tool for designers, control engineers, project engineers, and managers who desire to achieve the full cost and production benefits of implementing the 88 series.
