Control Engineering Top 5 most read articles online, for Apr. 20-26, covered inspecting instruments in hazardous locations, Apps for Engineers, industrial Internet programs and the cloud, feed forwards augmenting PID control, and enabling efficiency in continuous control. Link to each article below.

1. Inspecting instruments installed in hazardous locations

A difficult, time-consuming, and expensive task is made much simpler with wireless instruments to relay information from flow, pressure, temperature, level, and other field transmitters. 

2. Apps for Engineers: Easy calculations

CFE Media’s Apps for Engineers is an interactive directory of engineering-related applications for Apple iOS and Android operating systems form various companies. We’ve categorized apps by category, company, and type. This month, see these applications for making calculations easy. 

3. Launching industrial Internet programs into the cloud

Cloud service providers shorten the journey to the industrial Internet. Cloud services provide practical, low-cost, and adaptable solutions to address many aspects of the industrial Internet. 

4. Feed forwards augment PID control

Feed forward augmentation is a prediction technique that estimates the output from a proportional-integral-derivative (PID) control algorithm without waiting for the PID algorithm to respond. 

5. Enabling efficiency in continuous control

These 7 signs of a continuous process could indicate that the ISA 106 standard may offer effective and efficient help for continuous control operations beyond the scope of ISA 88 (originally written for batch, but applied well beyond that) or ISA 95 (used to connect operations with enterprise systems), according to a Dow Chemical Co. representative. 

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, April 20-26, for articles published within the last two months.
