Different programmable logic controllers (PLCs) handle PID control loops in different ways. Some loops need to be set manually, while others can use an autotune process embedded in the PLC's software.

But in many instances, no amount of adjustment of the proportional-integral-derivative (PID) parameters will make the loop behave as desired. When tuning fails, it is time to look outside the PID for ...

This seems easy ... common to “tune” a PID by setting Kp, Ki, and Kd constants that determine the “strength” of each action. With the beam, you can watch how tuning affects the system.

Allowing readers to develop professional competencies, this text is aimed at engineers and technicians who need a practical understanding of the essentials of process control, loop tuning and how to ...

As controls engineers delve into this field, one of their initial encounters with a control system is often with the PID controller, and this open source project delivers two of these general ...
