CD Automation announced the distribution of Lumel’s RE92 temperature and process controller. The advanced dual loop controller is ideally suitable for the most demanding industrial control ...

A technique called dual-loop control is sometimes used to compensate for instabilities caused by backlash. Backlash arises in systems where a motor is coupled to a load through gears or lead screws.

The method involves changing the triple-loop cascade control to a dual-loop control architecture with an integrated outer loop for position and speed control and an inner loop for current control.

This application note first briefly discusses the basic operation theory of a thermoelectric cooler (TEC) and its application in optical modules. Then it presents a digital approach to TEC control ...
