Control Engineering Top 5 most read articles online, for Apr. 13-19, covered feed forwards augmenting PID control, hacking oil and gas control systems, the relationship of torque and shaft size, collaborative robots and humans, and techniques for embedded system development. 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. Relationship of torque and shaft size

A rudimentary understanding of how shaft sizes are determined can be helpful to anyone who works with pumps, fans, elevators or any other motor-driven equipment. 

4. Collaborative robots and humans working together

Companies and researchers continue to work on developing robots that can work safely with humans on the factory floor without enclosures and be able to adapt and learn from human behavior. 

5. Six debugging techniques for embedded system development

Learning and propagating various debugging techniques reduces bug count and increases code quality. Here are six techniques that can go a long way in assisting the debugging process. Reset software coding expectations and get better results for embedded systems development. 

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, April 13-19, for articles published within the last two months.
