Programmable analogue chip firm Anadigm has developed software for implementing proportional, integral and derivative (PID) control loops. The tool allows the design of PID loops from top level ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...

Off-the-shelf motion controllers are a convenient and economical solution for most automation needs. But when applications demand more than the average off-the-shelf (OTS) controller can provide — ...

For the PDF version of this article, click here. More than 80% of the motors bought each year continue to be low-cost single-phase ac motors. Because these motors are not very efficient when ...

Proportional integral derivative (PID) control is the most common type of feedback control algorithm used in industry today. Because the PID algorithm can be tuned, it has been successfully used to ...
