Control Engineering Top 5 most read articles online, for Mar. 10-Apr. 9 covered feed forwards augmenting PID control, hacking oil and gas control systems, the 2015 Engineers' Choice winners, selecting and applying VFDs, and artificial intelligence for control engineering. 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. 2015 Engineers' Choice Awards winners

A total of 26 winners and 27 honorable mentions were named for the 2015 Engineers' Choice Awards, which were voted on by Control Engineering's print and digital audience. 

4. Selecting and applying VFDs

Clear understanding of the application, noise sources, and configuration parameters ensures peak variable speed drive (VFD) performance, efficiency, and reliability. 

5. Artificial intelligence for control engineering

Robotics, cars, and wheelchairs are among artificial intelligence beneficiaries, making control loops smarter, adaptive, and able to change behavior, hopefully for the better. 

The list was developed using CFE Media's web analytics for stories viewed on, March 10 to April 9, for articles published within the last two months.
