Control Engineering Top 5 most read articles online, for Apr. 8 to May 7, covered feed forwards augmenting PID control, hacking oil and gas control systems, the age of the control engineer, inspecting instruments in hazardous locations, and collaborative robots and humans working together. Link to each article below.

1. 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. 

2. Hacking oil and gas control systems: Understanding the cyber risk

Cyber attacks are growing in number and intensity over the past decade. Companies in the oil and gas industry are high-profile targets and must take measures to protect themselves from hackers. 

3. ‘The age of the control engineer is just dawning’

Dr. Peter Martin of Schneider Electric talked about opportunities to apply control engineering skills beyond efficiency at the Schneider Electric Global Automation Conference. 

4. Dirty pipelines decrease flow, production—pig your line

Allen Pennington, president of Pigs Unlimited International located in Tomball, Texas, shared his industry insights about the challenges related to pipeline cleaning. 

5. 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. 

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, April 8 to May 7, for articles published within the last two months.
