Figure 3: This process data from the level controller shows how it regulated separator output from several different input sources over a period of days, depicting the dramatic change in PID ...

A PID controller’s objective is to produce a control signal that can dynamically reduce the difference between the output and the desired setpoint of a given system. Consider the exemplary scheme ...

The PID controller itself seems fairly robust, and includes a number of features that seasoned controls engineers would look for in their PID controllers.

PID loops are a central component of modulating boiler control systems with applications ranging from basic steam header pressure control to cascading 3-element drum level control. A modern ...
