There are various ways in which computers can be used to control a process. First, we can distinguish between process monitoring and process control as illustrated in Figure 4.8.

The application of modern, automatic computer control techniques in industrial process control systems has been so limited --in­ deed, so surprisingly restricted --that it seems almost to disa­

Apr 24, 2025 · The modern computer process control system generally includes the following: (1) measurement of important process variables such as temperature, flow rate, and pressure, (2) execution of some optimizing strategy, (3) actuation of such devices as valves, switches, and furnaces that enable the process to implement the optimal strategy, and (4 ...

Process control refers to the set of techniques and tools used to monitor and adjust the variables of an industrial or research system. These variables can include temperature, pressure, flow, liquid levels, or motor speed, among other critical factors.

Jun 26, 2021 · The computer process control can be described as controlling a manufacturing process with the help of a digital computer. The automated system is operating by using a computer, the computer process control is specifically related to the continuous or semi-continuous operations.

This chapter introduces the concepts of hardware, software, and communication aspects of computer aided measurement and control systems and discusses techno-commercial benefits of such systems for its application in process industries.

Process Control Systems (PCS) play a pivotal role in optimizing and automating industrial processes, ensuring efficiency, reliability, and safety. These systems come in various types, each tailored to specific industrial applications.

Jun 27, 2019 · Essentially then, process control is all about eliminating human feedback – and allowing the advanced, automated systems of an industrial plant to handle minor adjustments automatically, without intervention beyond human monitoring of each system.

The use of computer systems in process control can provide great benefits, and it is estimated that efficiency can be increased by up to 30%. It is not surprising, therefore, that there have been considerable efforts by system designers and users to introduce and use such systems.

Factors that determine whether a computer controller can operate in realtime include: (1) the speed of the controller's central processing unit (CPU) and its interfaces, (2) the controller's operating system, (3) the design of the application software, and (4) the number of different input/out. put events to which the controlier is designed to ...
