A quick primer on Cascade Control featuring the mathematical modelling on how the system works.
The definition of a closed loop system is where the controlled variable is measured and this measurement is used to manipulate a process variable. Here follows a quick primer on sngle zone closed loop control.
Definition, example and mathematical model for open loop control
TIGHTENING CONTROL OF YOUR PROCESS BY UNDERSTANDING DIFFERENT TYPES OF CONTROL Process control covers a multitude of disciplines and technologies. Whether it be mass flow, fluid flow, pressure, position or temperature, the principles of control follow the same basic rules of measurement followed by adjustment of a process variable to maintain control of the process. The more precise the control, the more uniform and higher quality the end product, and, more importantly, the less the waste and the higher the profitability.
A primer on thermocouples - the most widely used temperature measurement devices - and also explores other instruments and devices to measure, and subsequently control, temperature in industrial processes. The versatile thermocouple is the most widely used industrial temperature-measurement device... Read the final installment of a two part article as published in Process Cooling magazine
The materials of construction, temperature range, accuracy and control requirements for each type of temperature-measuring device varies, but the key function remains the same. Read the first installment of a two part article as published in Process Cooling magazine
The struggle in maintaining aging automation platforms is very real. According to ARC Advisory Group, there are $65 billion worth of installed distributed control systems (DCSs) nearing their end of life, with many of those systems over 25 years old.
