Take Advantage of the Opportunities at ISA’s Fall Leaders Meeting

The ISA Fall Leaders Meeting (FLM)—which will get underway later this month in Tampa, Florida—brings ISA leaders together to assess the state of the Society, consider strategies and actions to improve operational results, conduct training sessions for new leaders, plan for leadership succession, celebrate achievements, and promote fellowship. For the seasoned member and/or leader, it […]

Applications of Thermoelectric Modules on Heat Flow Detection

Abstract: This paper presents quantitative analysis and practical scenarios of implementation of the thermoelectric module for heat flow detection. Mathematical models of the thermoelectric effects are derived to describe the heat flow from/to the detected media. It is observed that the amount of the heat flow through the thermoelectric module proportionally induces the conduction heat owing […]

Fault-Tolerant-Synchronization-of-Chaotic-Gyroscope-Systems

Fault Tolerant Synchronization of Chaotic Heavy Symmetric Gyroscope Systems

Abstract: In this paper, fault tolerant synchronization of chaotic gyroscope systems versus external disturbances via Lyapunov rule-based fuzzy control is investigated. Taking the general nature of faults in the slave system into account, a new synchronization scheme, namely, fault tolerant synchronization, is proposed, by which the synchronization can be achieved no matter whether the faults and […]

A New and Different Direction for ISA

The classic definition of insanity is to keep doing the same things you have been doing and expecting different results.  At some point, you have to nudge things along in an attempt to affect a change and move in a positive direction. Last month, ISA’s Executive Board decided it was time to change what we […]

Hybrid-Intelligent-Method-for-Recognition-of-Common-Types-of-Control-Chart-Patterns

Hybrid Intelligent Method for Recognition of Common Types of Control Chart Patterns

Abstract: Automatic recognition of abnormal patterns in control charts has seen increasing demands nowadays in manufacturing processes. This paper presents a novel hybrid intelligent method (HIM) for recognition of the common types of control chart pattern (CCP). The proposed method includes two main modules: a clustering module and a classifier module. In the clustering module, the […]

Stabilization-of-Linear-Time-Invariant-Fractional-Order-Switched-Systems

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 […]

How-Much-Is-Enough-Cybersecurity-Protection-for-an-Industrial-Network

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, […]

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 […]

An Efficient Decentralized Iterative Learning Tracker

Abstract: In this paper, an efficient decentralized iterative learning tracker is proposed to improve the dynamic performance of the unknown controllable and observable sampled-data interconnected large-scale state-delay system, which consists of NN multi-input multi-output (MIMO) subsystems, with the closed-loop decoupling property. The off-line observer/Kalman filter identification (OKID) method is used to obtain the decentralized linear models […]
