Control Engineering Top 5 most read articles online, for Sept. 29 to Oct. 5, open- vs. closed-loop control, Wi-Fi terms and definitions, four advantages of state-based controls, nano sensors, and wireless propagation fundamentals. Link to each article below.

1. Open- vs. closed-loop control

Automatic control operations can be described as either open-loop or closed-loop. The difference is feedback. 

2. Wi-Fi acronyms, wireless buzzwords, WLAN nomenclature, wireless terms

Industrial wireless tutorials: WLANs (wireless local area networks) have a language, an "alphabet soup" of acronyms and buzzwords designed to facilitate deeper discussions of the technology used. 

3. Four advantages of state-based control

State-based control may increase your workload at first, but the benefits start to kick in and earn their worth quickly. 

4. Nano sensors, everywhere

Think Again: Micromachining techniques are shrinking sensors, making devices less expensive with more capabilities. Microelectrical mechanical systems (MEMS) will evolve into nanoelectrical mechanical systems (NEMS). 

5. Wireless propagation fundamentals

Industrial wireless tutorials: Understanding wireless propagation fundamentals will help you understand what can happen to a wireless signal and how that can influence wireless signal reliability. Learn the 4 results of multipath. 

The list was developed using CFE Media's web analytics for stories viewed on, September 29 to October 5, for articles published within the last two months.
