For example, when migrating from a PLC to a DCS, the PID tuning parameters are converted directly to the proper units and time bases for the algorithm choice. This maintains the established dynamic ...

Brushless DC motors, and their associated drive electronics, tend to be expensive and complicated. [Ottoragam] was looking for a cheaper alternative and built this Brushed DC motor servo controller… ...

Proportional integral derivative (PID) control is a common method used to regulate the dynamic behavior of a system. Examples are found in many industrial devices, where it’s employed for ...
