The top 5 most read articles online, from Nov. 7-13 for Control Engineering, covered three-phase motor operation, PID velocity, PLC object-oriented programming benefits, the Engineers’ Choice finalists, and scary automation on Halloween. Links to each article below. 

1. How to properly operate a three-phase motor using single-phase power

There are several methods to operating a three-phase motor using single-phase power to make what would be an otherwise expensive and arduous process a little easier.

2. The velocity of PID 

Inside Process: Proportional-integral-derivative (PID) theory is best introduced as the familiar second order differential equation via the velocity form instead of the more traditional positional form. 

3. PLC object-oriented programming benefits

Object-oriented programming (OOP) is about organizing and simplifying program elements in an optimal way by using objects, methods, and properties. 

4. 2017 Engineers’ Choice Finalists 

For a limited time, the official Engineers’ Choice ballot is open for voting for Control Engineering North American print and digital edition subscribers. Vote for the best Engineers’ Choice finalists of 116 entries across 28 categories. 

5. Using automation to scare the neighbors on Halloween

Automation is used in ghoulish and frightful ways by one particular sales manager on Halloween who is determined to satisfy his children’s urge and desire to scare. See video for more frights and scares.

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, November 7-13, for articles published within the last two months.
