Money spent to reduce deadtime (e.g. greater agitation, faster valves, faster measurements) will be wasted if the controller is not tuned faster. You may have wonderful process dynamics but loop performance will be lousy if the PID is not tuned to be commensurate with the opportunity. A loop with excessively slow tuning and low deadtime […]

By Terry Blevin Single-loop and multi-loop control may be used to address a wide variety of control requirements. However, if a process is characterized by extremely long process delays or by a high degree of process interaction, then other control techniques may be required. In Chapter 16 of Control Loop Foundation – Batch and Continuous […]
IT can help create a secure network connection to the industrial plant floor. It can be ideal for a machine builder to monitor and connect to a piece of equipment in a plant remotely. However, how many machine builders have tried to cross that invisible barrier? As soon as you mention you want to open […]
Control Engineering 40 Under 40 is a recognition program designed to identify and give recognition to young engineers who have made significant contributions toward the control engineering profession. Help us get young people interested in engineering. We’re seeking successful and well-rounded control-engineering-minded individuals 18 or older and under 40 years of age (as of Nov. […]
A continuous chemical reactor process is characterized by the continuous feed of two or more chemical reactants and a continuous output flow of product. To achieve the desired product specifications, the proportions of each reactant must be tightly maintained at a target value using ratio control. The chemical reaction that occurs within the reactor is […]
As mentioned in my previous blogs on the book Control Loop Foundation – Batch and Continuous Processes, the application examples included in Chapter 16 illustrate the various ways single loop and multi-loop control techniques may be used automate plant control. The second workshop exercise in this chapter allows the reader to explore the different features […]
