Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

The characteristic of the object, i.e. the lag time, is generally a pure lag or a capacity lag. The former is generally caused by the time required for material transmission in the process section, and the latter is generally caused by the time required for heat exchange of a controlled object and the continuous passing of the material through a plurality of containers to establish a stable signal. The clear point is that the true value of the temperature can be displayed only after the sub-reaction does not occur.

In closed loop temperature control, a PID temperature controller is used to solve this problem. The key is D (differential control) in PID, and the effect of the differential control is the advance control. Assuming that the temperature of the material needs to be controlled, the temperature is controlled to be 35 ℃ (35 ℃ is the target value). The PID control includes P, PI, PD, PID, etc., and the PID control is selected in consideration of the temperature as the controlled variable.

The temperature sensor detects the temperature, the temperature value obtained at the moment can be compared with a target value (35 degrees) to obtain deviation, then the controller judges and quickly makes processing judgment to send a signal to the actuator to adjust the temperature, a new dynamic temperature steady-state value can be obtained at the moment, the temperature sensor can send the value signal to the controller to be compared with the target value to obtain a residual difference, I integral control intervention is needed, the temperature controller sends a signal to the actuator to adjust the temperature again after processing judgment, and after new dynamic stability is achieved, the new steady-state value is transmitted to the controller to be compared with the target value or D differential control intervention is needed. Therefore, PID parameter setting is a tedious process, and finding three ideal PID control parameter values for improving control quality sometimes takes a lot of time.

PID parameter setting is needed to realize the dynamic stability of temperature control to be about 35 degrees. Proportional, integral and differential. The temperature controller can automatically adjust the PID and can also manually adjust the PID.
