thereby controlling external devices or circuits.
When using a PI controller, the output of the I-controller is limited within a certain range, overcoming integral saturation, where the transition of the integral output, even as the zero error state increases, is due to the nonlinear conditions of the plant.

D-controller
The I-controller does not have the ability to predict erroneous future behavior. So once the set value changes, it will react normally. The D controller overcomes this problem by predicting future erroneous behavior. Its output depends on the rate of change of error relative to time, multiplied by a differential constant. It provides startup for output, thereby increasing system response.

In the above figure, the response of the D controller is higher than that of the PI controller, and the establishment time of the output is also reduced. It improves the stability of the system by compensating for the phase lag caused by the I controller. Increasing the differential gain will improve the response speed.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 1C31179G02 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
