thereby controlling external devices or circuits.
(1) High precision control: The PID controller can accurately adjust the control quantity based on system deviation, achieving high-precision control. By optimizing the parameters of the PID controller (proportional coefficient Kp, integral coefficient Ki, and differential coefficient Kd), the control accuracy of the system can be further improved.
(2) Fast response: the differential control item in the PID controller can predict the change trend of system deviation, adjust the control quantity in advance, thus accelerating the system response speed. This enables the PID controller to quickly restore a stable state in the face of external disturbances or parameter changes.
(3) Good stability: The integral control term in the PID controller can gradually reduce steady-state errors, stabilizing the system output near the set value. This makes the PID controller have good stability and suitable for systems that require long-term stable operation.
3、 Working principle and characteristics of switch controller
working principle
A switch controller is a threshold based control strategy that outputs only two states: “on” and “off”. When the output value of the controlled object exceeds or falls below the set threshold, the switch controller will switch the output state. For heating control, when the temperature is below the set value, the output is “on” and the heating equipment starts working; When the temperature exceeds the set value, the output is “off” and the heating equipment stops working. The working principle of the switch controller is simple and intuitive, suitable for situations where control accuracy is not required.
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 1X00781H01 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.
