Stabilization of Linear Time Invariant Fractional Order Switched Systems

Abstract: This paper presents the stabilization problem of a linear time invariant fractional order (LTI-FO) switched system with order 1<q<21<q<2 by a single Lyapunov function whose derivative is negative and bounded by a quadratic function within the activation regions of each subsystem. The switching law is extracted based on the variable structure control with a sliding […]

Should STEM Education Programs Include the Arts?

Michael J. Gelb, author of the book How to Think like Leonardo da Vinci, gave a thought-provoking keynote presentation at an Emerson Exchange. He posed the notion that STEM (science, technology, engineering, and math) education should be expanded to STEAM (science, technology, engineering, art, and math) education. Certainly his presentation about Leonardo da Vinci and his […]

How Much Is Enough Cybersecurity Protection for an Industrial Network?

Today’s cyber threat landscape is constantly changing with a growing list of highly publicized attacks against the government, retail stores, and business information networks. The number of incidents against industrial networks is also growing—and they often go unreported. Most of today’s industrial networks are not isolated from corporate business networks or the Internet. In fact, […]

How to Integrate Valve Actuators with an Automation System

There are two key issues currently affecting the actuation industry: host system integration and functional safety. Host system integration In any plant installation, a key requirement is being able to smoothly integrate the actuators used for opening or closing valves with the plant’s automation system. While the mechanical interface between actuator and valve is standardized, […]

Unintended Consequences of Cutting Technical Headcount

In the automation community, we routinely hear that reducing head count is one of the better ways to cut operational costs in a manufacturing plant. From some perspectives, this assertion makes sense, especially if management is looking for short-term cost reductions to bolster the plant’s net operating profits, meet their performance goals, and receive their […]
