Improving the Performance of a Model Predictive Controller for Regulatory Control [Technical]
Automation engineers investigate several commonly used control structures such as “Cascaded PI controller,” “DMC cascaded to PI” and “Direct DMC.” -
The Three Most Desirable MRP Software Features for Manufacturers
For manufacturers, material requirements planning (MRP) software is one of the key elements to running a smooth manufacturing operation. -
AutoQuiz: What Are Multiple Independent Protection Layers in Relation to Industrial Safety?
A consequence of the concept of multiple independent protection suggests minimization of risk occurs when safety instrumented systems are completely independent from process control systems. -
Three Decades of Life with Pipeline Leak Detection
At a time when detecting large industrial pipeline leaks within the same day was challenging, new technology that could detect small leaks and any leak quickly was exciting. -
AutoQuiz: What Is the Response in Level Control System If the Process Liquid Medium Changes?
For a capacitance probe installed in a metal tank, the measured level is proportional to the measured capacitance between the level probe (one capacitor plate) and the tank wall (second capacitor plat -
How the IIoT Puts Factory Electrical Systems at Risk and What You Can Do About It
Factories of the future will demand advanced circuit protection technology to keep everything connected. -
Redefine and Transform How You Execute Automation Projects
Improving on what has always been done can only result in incremental improvements at best or continued complications. We have to redefine and transform how we execute automation projects. -
AutoQuiz: How to Determine Cause of the Apparent Discrepancy in Flow
Periodic visual inspection of orifice plates is required to ensure the integrity of measurement with a digital flow transmitter. -
PID Controller Design for Indirect Vector-Controlled Induction Motor [Technical]
Decoupling of the stator currents is important for smoother torque response of indirect vector controlled induction motors. -
AutoQuiz: Which Flowmeter Type Does Not Operate on the Principle That a Differential Pressure Is Developed Across a Flow Restriction?
A Coriolis flowmeter develops a flow measurement by measuring the degree of deformation (twisting) of a vibrating tube(s) as the fluid moves through the tube. -
