How Do You Balance Connectivity with Security on the Plant Floor?

Manufacturing facilities increasingly are becoming reliant on network connectivity to improve operational efficiency.  Getting an internet connection on the plant floor without running it through the enterprise IT department is quick and it gets the job done – as long as the network is only connected when your equipment or software vendor is providing remote […]

Can Variable-Speed Drives Increase Process Efficiency and Reduce Energy Use?

There is a high potential to reduce pumping-energy-consumption cost through properly designing and selecting the pumping system and controls. Electrical motor-driven pump systems account for nearly 20 percent of the world energy use and 25-50 percent of the total electrical energy use in certain industrial facilities. Pump energy consumption is often one of the larger […]

Why Is Instrumentation Critical for the Automation Professional?

This tip is actually a compilation of Tip #1 “Never Stop Learning” and Greg’s tip on “Seek Principles,” Tip #66. As a young engineer I spent a great deal of time and effort learning how instrumentation worked. Once I had a thorough understanding of that information, I could evaluate competing instrumentation designs and better select […]

Robust Vibration Control at Critical Resonant Modes Using Indirect-Driven Self-Sensing Actuation in Mechatronic Systems

Abstract: This paper presents an improved indirect-driven self-sensing actuation circuit for robust vibration control of piezoelectrically actuated flexible structures in mechatronic systems. The circuit acts as a high-pass filter and provides better self-sensing strain signals with wider sensing bandwidth and higher signal-to-noise ratio. An adaptive non-model-based control is used to compensate for the structural vibrations […]
