Control Engineering Top 5 most read articles online, for Oct. 27 to Nov. 2, covered the 2015 Engineers’ Choice Awards Finalists, dual loop motion control, avoiding reuse on an automation project, fieldbus device couplers used in a chemical plant upgrade, and support-focused enterprise controls. Link to each article below.

1. 2015 Engineers’ Choice Awards Finalists

The Control Engineering 2015 Engineers’ Choice Awards program features 94 finalists across 26 categories. Voting will close on Dec. 31, 2014; Details and photos are available for each product. 

2. Dual loop motion control with one encoder

Motion control system example shows how mechanical stiffness can improve by a factor of 100. Dual loop control, often used to improve the secondary feedback device, is simpler when second encoder functionality is integrated in the motor. 

3. Avoid the pitfalls of ‘reuse’ on your automation project

When used appropriately, reuse can dramatically reduce the upfront engineering time and cost for a new project. 

4. Next-generation fieldbus device couplers simplify chemical plant upgrade

Petrochemical plant adds new physical-layer technology to its long-running fieldbus networks. 

5. Support-focused enterprise controls series

This article is the introduction for a series of five articles that explore the critical components of a support-focused controls system. 

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, October 27 to November 2, for articles published within the last two months.
