The top 5 most read articles online, from Oct. 3-9 for Control Engineering, covered PID velocity, VFD software advantages, SIF validation procedures, process control simulation, and a system integrator acquisition. Link to each article below. 

1. 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. 

2. Taking advantage of VFD software

Although VFD manufacturers have made many advances in terms of ease of use, some users still find programming and monitoring with a 2-inch display tedious. This is where VFD programming and monitoring software comes into play.

3. Creating SIF validation procedures 

Implementing safety system validation as part of the safety lifecycle is defined by IEC 61511 and ANSI/ISA-S84.01. Here’s how it’s done.

4. Process control simulation benefits

Process controls simulation can serve as a powerful and effective tool for training operators and assess safety and environmental risks.

5. System integrator acquired by automation company

Rockwell Automation has acquired systems integrator company Maverick Technologies in an effort to expand their control and information solutions.

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, October 3-9, for articles published within the last two months.
