摘要:A universal three-element digital control system is described which forms aproportional signal, an integral signal and a derivative (differential) signal from an errorsignal and combines such signals to provide a controlling output signal to a device beingcontrolled. The error signal is the difference between the actual signal, representative ofthe actual condition of the device being controlled, and the setpoint, which is
representative of the desired condition. The proportional signal is proportional to theerror signal. The integral and differential signals can be approximated by combining theprevious error signals with the present error signal. Offset and multiplying elements areprovided by which each of the signals can be offset or proportionalized to customize thecontrol system for a particular application.
