Is the Internet of Things Creating Unfocused Urgency to Monitor Everything?

Business analysts, industry consultants, venture capitalists, and major vendors are forecasting enormous Internet of Things (IoT) growth with estimates of massive numbers of sensors being deployed to instrument everything. Executive management at companies are being bombarded with an overwhelming message: if they do not invest in the adoption of IoT technologies, their competitors will dramatically […]

How to Use HMIs to Improve Energy Efficiency and Reduce Power Consumption

Machine and process skid builders can use human-machine interface (HMI) software to improve energy efficiency by measuring and monitoring energy usage, and by then using this data to reduce energy consumption through analysis and optimization. Through their connection to a variety of monitoring devices and controllers, HMIs provide measurement and monitoring and save the data […]

How to Select Specialized Instrumentation for Temperature Measurement

Many temperature applications in the oil and gas, petrochemical, and other industries involve demanding process conditions, hazardous media, elevated corrosion rates, turbulence, vibration, and high pressures and temperatures. In these instances, specialized instrumentation, such as multipoint thermometers, skin-point thermometers, or high-temperature/harsh-environment devices, are available to make the required measurements. For temperature profiling, multipoint thermometers allow […]

How to Succeed with the Industrial Internet of Things

More than just hype, the Industrial Internet of Things (IIoT) offers significant potential value for manufacturers and other industrial organizations. The key is to create a long-term vision with an associated value proposition, identify the right applications to target initially, and employ the appropriate operational and information technologies, much of which is likely either already […]

New Missile Guidance Law for Moving Targets

Abstract: A novel nonlinear missile guidance law against maneuvering targets is designed based on the principles of partial stability. It is demonstrated that in a real approach which is adopted with actual situations, each state of the guidance system must have a special behavior and asymptotic stability or exponential stability of all states is not realistic. […]

Design of a Self-Tuning Regulator for Temperature Control of a Polymerization Reactor

Abstract: The temperature control of a polymerization reactor described by Chylla and Haase, a control engineering benchmark problem, is used to illustrate the potential of adaptive control design by employing a self-tuning regulator concept. In the benchmark scenario, the operation of the reactor must be guaranteed under various disturbing influences, e.g., changing ambient temperatures or impurity […]

Position Control of a Servo-Hydraulic Rotary Actuator Via a Neurobiologically Motivated Algorithm

Abstract: This paper presents a new intelligent approach for adaptive control of a nonlinear dynamic system. A modified version of the brain emotional learning based intelligent controller (BELBIC), a bio-inspired algorithm based upon a computational model of emotional learning which occurs in the amygdala, is utilized for position controlling a real laboratorial rotary electro-hydraulic servo (EHS) […]

Protecting Airport Power with Automatic Transfer Switches

Singapore’s Changi Airport is the 18th busiest in the world. In 2014, it served more than 40 million passengers and 1.8 million tons of air freight. Airport systems are critical nerve centers of the global economy, and it is important that they keep running, regardless of power outages or power disruptions. Airports rely on backup […]
