  • Process plants consist of hundreds, or even thousands, of control loops all networked together to produce a product to be offered for sale. Each of these control loops is designed to keep some important process variable such as pressure, flow, level, temperature, etc. within a required operating range to ensure the quality of the end product. Each of these loops receives and internally creates disturbances that detrimentally affect the process variable, and interaction from other loops in the network provides disturbances that influence the process variable....

  • In a 2004 survey of 200 IT professionals from 14 countries in the Americas, Asia/Pacific and Europe, the IT Governance Institute (ITGI) found that in 80% of organizations, IT management is solely responsible for defining and addressing IT risk impact. This widespread lack of involvement by business unit managers demon- strates a consistent—and alarming—gap in mapping technology risk to the business. Additionally, this gap als shows that most organizations have inadequate IT risk assessment processes across their enterprises.

  • A PLC or programmable controller is a computer based solid state device that controls industrial equipment and processes. Initially designed to perform the logic functions executed by relays, drum switches and mechanical timer/counters, it has been extended to analog control as well. A typical PLC system consists of a processor and an input/output system all mounted in a rack like system. The PLC system is a cost effective solution for applications with a high ratio of digital to analog points in a system.

  • This book will discuss the topic of Control Systems, which is an interdisciplinary engineering topic. Methods considered here will consist of both "Classical" control methods, and "Modern" control methods. Also, discretely sampled systems (digital/computer systems) will be considered in parallel with the more common analog methods. This book will not focus on any single engineering discipline (electrical, mechanical, chemical, etc), although readers should have a solid foundation in the fundamentals of at least one discipline....
