It is a common situation in electronics to have a control loop, that is some sort of feedback that drives the input to a system such as a motor or a heater based upon a sensor to measure something ...

The controller contains the “control algorithm,” or control logic equation. The most common control algorithm is called PID, which stands for Proportional (P)-Integral (I)-Derivative (D). When the ...

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 ...
