Control Station supplies PID tuning software to Rockwell Automation

Control Station's LOOP-PRO TUNER PID controller tuning software is integrated within the PlantPAx engineering workstation.

ExperTune introduces Virtual Classroom for PID Training

The interactive training is provided by a live instructor, and includes hands-on practice using ExperTune’s “Virtual Classroom.”

Ziegler-Nichols Tuning Rules And Limitations

The standard reference for PID tuning seems to be the Ziegler-Nichols tuning rules developed in 1942 on a pneumatic controller.

The Fast Way to Tune Slow Loops

To tune a control loop, analysis software must process some loop data. You must test or bump the loop somehow. For example a setpoint change in automatic or a controller output change in manual mode. 

Derivative Action - The Good, Bad, and Ugly

The reason to use derivative (or D) is that you can use more Proportional and especially more Integral action. The result can be a much faster reacting control loop.
