Microcomputers in Process Control

Abstract

Computers have been extensively used for process control and optimization since the 1970's. Many articles have been published documenting the benefits of computer control; and in general, energy savings of 5% or greater versus the baseline control system have been achieved. ln addition, second generation programs that take advantage of reduced digital electronic hardware costs and utilize new program applications can produce additional benefits. Future developments in digital control systems, facility coordination, customer integration, and company wide energy management programs will ensure the process industries continued utilization of microcomputers throughout the plant, even with the current decrease in the price of oil.
