Control Engineering Top 5 most read articles online, for Nov. 10-16, covered tuning PID loops for level control, manually configuring smart devices, control system programming, automation vs. headcount, and optimizing servo controls. Link to each article below.

1. Tuning PID loops for level control

One-in-four control loops are regulating level, but techniques for tuning PID controllers in these integrating processes are not widely understood. 

2. Automating automation: Why do smart devices have to be configured manually?

While smart instrumentation and field devices have highly sophisticated capabilities, configuration is still a mostly manual process. Users want to know why they still have to perform this action (and many others) the hard way. 

3. Control system programming: More design time, less implementation time

Lazy?! Great control system programmers spend more time in design so they can spend far less time in the implementation stage. While this might seem that you need to be lazy to be a great control system programmer, you’re just being smart, efficient, and thrifty with programming time and budget.  

4. How many people will be running your plant?

Process manufacturers have to deal with basic head count challenges. The answer may be fewer people than you think, but how do you find the right number? 

5. Optimizing servo control with an adaptive nonlinear algorithm

Servo control software improves applications requiring accurate path tracking and low settling time, such as CNC and cutting, conveyor tracking, pick-and-place operations, PCB mounting, welding, as well as painting, coating, and gluing. 

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, November 10-16, for articles published within the last two months.
