Advanced Regulatory Control

Book Description

Without modern Instrumentation control, industry would be at a standstill. Whether the instrumentation control hardware consists of local mechanical, pneumatic, or electronic controls, electronic or pneumatic analog controllers, microprocessor-based controllers, programmable logic controllers, personal computer-based controls, or a distributed control system, a keen awareness of advanced regulatory control is required by engineers, technicians, and technical managers in order that appropriate control technology be applied to industrial processes. This book is intended to describe advanced regulatory control and its application to continuous processes in a nonmathematical format and in as practical a manner as possible in order to be of benefit to all skill levels. Both manual and regulatory control are described in the text as a prelude to advanced regulatory control so that their differences might be explored.
