The Art of Level Instrument Selection

In the January/February 2013 issue of InTech, Donald Gillum wrote an excellent article titled Level Measurement: Determining Interface Position Between Two Media. In that article, Gillum discussed the various types of level instrumentation used by industry today and described how they work and some of the advantages and disadvantages of each. This article is a follow-up […]

Becoming an Automation Professional: Network, Educate, Innovate

I moved with my family to America from Russia in the early 2000s. Upon entering college in 2003, I had a fairly good idea of what I wanted from my education. After taking classes at Louisiana State University and the University of Southern Mississippi (USM), I graduated with a bachelor’s degree in computer engineering technology […]

Adaptive Backstepping Sliding Mode Control of Flexible Ball Screw Drives

Abstract: This paper presents a method to model and design servo controllers for flexible ball screw drives with dynamic variations. A mathematical model describing the structural flexibility of the ball screw drive containing time-varying uncertainties and disturbances with unknown bounds is proposed. A mode-compensating adaptive backstepping sliding mode controller is designed to suppress the vibration. […]

A Behind-the-Scenes Look at a Calibration Process Change

    After you have made the decision to get out of your calibration rut, the next step is to outline a system implementation process. Remember that implementing a fully integrated, automated calibration solution is a process. It simply won’t happen overnight, and needs to be done in steps. Before talking about the steps, let’s […]

Four Myths About Why We Have a Shortage of Engineers

There seems to be a wealth of articles detailing the problems the automation industry has finding and developing new talent. There are statistics that say there is a shortage of STEM (science, technology, engineering, and mathematics) students in our universities, that there are not dedicated degrees that focus on automation, and that the demographics in […]

Creating Twenty-First Century Learning Systems

A highly skilled workforce is the lifeblood of any successful company, industry, or national economy. The U.S. has been the breeding ground for the world’s most innovative economy, companies, and products in large part because it offered a diverse pool of talented, highly educated workers. But evidence of a decline is surfacing, precipitated by three […]

Generalized Eigenvalue Minimization for Uncertain First-Order Plus Time-Delay Processes

Abstract: This paper shows how to apply generalized eigenvalue minimization to processes that can be described by a first-order plus time-delay model with uncertain gain, time constant and delay. An algorithm to transform the uncertain first-order plus time delay model into a state-space model with uncertainty polyhedron is firstly described. The accuracy of the transformation is […]

Leveraging Big Data in Real Time

Most manufacturing plants hold weekly or monthly production meetings where they review productivity and waste. Obviously, the reports do not let them change what has happened in the past, yet in most cases, they also provide little insight into how to change the future. Many are stuck in a paradigm of “inspect and reject.” This […]
