An application-oriented approach to process control. The reference text systematically explains process identification, control and optimization, the three key steps needed to solve a multivariable control problem. Theory is discussed as far as it is needed to understand and solve the defined problem, while numerous examples written in MATLAB illustrate the problem-solving approach.
Techniques such as dead time compensation, adaptive control and Kalman filtering have been around for some time, but as yet find little application in industry. This is due to several reasons, including: Articles in the literature usually assume that the reader is familiar with a specific topic and are therefore often difficult for the practicing control engineer to comprehend. Many practicing control engineers in the process industry have a chemical engineering background and did not receive a control engineering education. There is a wide gap between theory and practical implementation, since implementation is primarily concerned with robustness, and theory is not. The user therefore has to build an "expert shell" in order to achieve the desired robustness. Little is published on this issue, however. This book tries to promote the use of advanced control techniques by taking the reader from basic theory to practical implementation. It is therefore of interest to practicing control engineers in various types of industries, especially the process industry. Graduate and undergraduate students in control engineering will also find the book extremely useful since many practical details are given which are usually omitted in books on control engineering. Of special interest are the simulation examples, illustrating the application of various control techniques. The examples are available on a 5-1/4" floppy disk and can be used by anyone who has access to LOTUS 1-2-3. Chapter 1 is the introduction; Chapters 2 through 6 deal with distributed control system networks, computer system software, computer system selection, reliability and security, and batch and continuous control. Chapter 7 gives and introduction to advanced control. Chapters 8 through 11 deal with dead time compensation techniques and model identification. Chapters 12 through 14 discuss constraint control and design, and the adjustment and application of simple process models and optimization. Chapter 15 gives a thorough introduction to adaptive control, and the last two chapters deal with state and parameter estimation. This book is a valuable tool for everyone who realizes the importance of advanced control in achieving improved plant performance. It will take the reader from theory to practical implementation.

The Second Shell Process Control Workshop covers the proceedings of a workshop of the same name, held in Houston, Texas on December 12-16, 1988. The said workshop seeks to improve the communication process between academic researchers, industrial researchers, and the engineering community in the field of process control, and in turn improve understanding of the nature of the control problems. The book covers topics such as automatic tuning and adaptive control; an operator control theory approach to the shell standard control problem; discrete time-adaptive predictive control; and the designing of a control system. Also included are topics such as optimal control and model identification; fundamental process control; statistical process control; and interfaces with process control. The text is recommended for researchers and practitioners in the field of engineering who would like to know more about process control and modeling.

“We are not worth more, they are not worth less.” This is the mantra of S. Brian Willson and the theme that runs throughout his compelling psycho-historical memoir. Willson’s story begins in small-town, rural America, where he grew up as a “Commie-hating, baseball-loving Baptist,” moves through life-changing experiences in Viet Nam, Nicaragua and elsewhere, and culminates with his commitment to a localized, sustainable lifestyle. In telling his story, Willson provides numerous examples of the types of personal, risk-taking, nonviolent actions he and others have taken in attempts to educate and effect political change: tax refusal—which requires simplification of one’s lifestyle; fasting—done publicly in strategic political and/or therapeutic spiritual contexts; and obstruction tactics—strategically placing one’s body in the way of “business as usual.” It was such actions that thrust Brian Willson into the public eye in the mid-’80s, first as a participant in a high-profile, water-only “Veterans Fast for Life” against the Contra war being waged by his government in Nicaragua. Then, on a fateful day in September 1987, the world watched in horror as Willson was run over by a U.S. government munitions train during a nonviolent blocking action in which he expected to be removed from the tracks and arrested. Losing his legs only strengthened Willson’s identity with millions of unnamed victims of U.S. policy around the world. He provides details of his travels to countries in Latin America and the Middle East and bears witness to the harm done to poor people as well as to the environment by the steamroller of U.S. imperialism. These heart-rending accounts are offered side by side with inspirational stories of nonviolent struggle and the survival of resilient communities Willson’s expanding consciousness also uncovers injustices within his own country, including insights gained through his study and service within the U.S. criminal justice system and personal experiences addressing racial injustices. He discusses coming to terms with his identity as a Viet Nam veteran and the subsequent service he provides to others as director of a veterans outreach center in New England. He draws much inspiration from friends he encounters along the way as he finds himself continually drawn to the path leading to a simpler life that seeks to “do no harm.&rdquo Throughout his personal journey Willson struggles with the question, “Why was it so easy for me, a ’good’ man, to follow orders to travel 9,000 miles from home to participate in killing people who clearly were not a threat to me or any of my fellow citizens?” He eventually comes to the realization that the “American Way of Life” is AWOL from humanity, and that the only way to recover our humanity is by changing our consciousness, one individual at a time, while striving for collective cultural changes toward “less and local.” Thus, Willson offers up his personal story as a metaphorical map for anyone who feels the need to be liberated from the American Way of Life—a guidebook for anyone called by conscience to question continued obedience to vertical power structures while longing to reconnect with the human archetypes of cooperation, equity, mutual respect and empathy.
This book does not offer any miracles, although it does offer a better opportunity for someone to get results, for one who is prepared to get out of the victim role and take a positive step into seeing what they can do for themselves. By reading this book, you will realise the significance of continuous learning. And that’s how philosophy tries to discover the nature of truth and knowledge, to find what is of basic value and importance in life. This is about the relationships between humanity and nature and between the individual and the society.
After serving in the Vietnam War, S. Brian Willson became a radical, nonviolent peace protester and pacifist, and this memoir details the drastic governmental and social change he has spent his life fighting for. Chronicling his personal struggle with a government he believes to be unjust, Willson sheds light on the various incarnations of his protests of the U.S. government, including the refusal to pay taxes, public fasting, and, most famously, public obstruction. On September 1, 1987, Willson was run over by a U.S. government munitions train during a nonviolent blocking action in which he expected to be removed from the tracks. Providing a full look into the tragic event, Willson, who lost his legs in the incident, discusses how the subsequent publicity propelled his cause toward the national consciousness. Now, 23 years later, Willson tells his story of social injustice, nonviolent struggle, and the so-called American way of life.
An only child living in Aldershot, Brian Stuart has always been in touch with the arts. When his father was called up to the army in 1940 his mother decided to take in boarders who performed weekly in the Hippodrome.
When God created human beings, He gave them the capacity and desire for pleasure. Human entertainment can glorify the Lord by expressing joy and creativity. But when unrestrained, it often degenerates into self-gratification.
