Coefficient determination method and device, electronic equipment, PID system and storage medium

Abstract

The invention relates to a coefficient determination method and device, electronic equipment, a PID system and a storage medium. According to the method, parameters are adjusted according to a PID coefficient combination composed of a current proportionality coefficient, a differential coefficient and an integral coefficient; the time consumed when the initial values of the parameters are adjustedto meet the condition is obtained; when the consumed time is determined to be larger than a time threshold value, one or more of the proportionality coefficient, the differential coefficient and theintegral coefficient are adjusted, wherein the values of the proportionality coefficient, the differential coefficient and the integral coefficient before and after adjustment are located in corresponding preset range intervals respectively. In the process, the electronic equipment can simply and quickly determine a proper PID coefficient combination, so that the control and adjustment time of theto-be-controlled system is shortened. Because the electronic equipment controls and adjusts the system to be controlled for a long time, the overall control and adjustment efficiency can be improvedthrough temporary time consumption for a long time.

Description

technical field [0001] The application belongs to the field of parameter adjustment, and in particular relates to a coefficient determination method, device, electronic equipment, PID system and storage medium. Background technique [0002] PID (proportion integration differentiation, proportional-integral-differential) control is a control adjustment algorithm, through the adjustment of proportional, integral, and differential, the current value can be adjusted to a preset preset value. Of course, adjusting the current value to the preset value is not a one-time process. For the PID system, once the current value and the preset value are set, the PID system will automatically go through multiple rounds of adjustments, so that the current value will approach the preset value. [0003] In the PID control adjustment algorithm, proportional, integral, and differential all have a corresponding coefficient, which are P, I, and D coefficients respectively. The PID coefficient di...

Problems solved by technology

However, in the prior art, when the PID system is applied to the system to be controlled, the corresponding PID coefficients are usually manually set for the PID system through experience, which may cause the final obtained PID coefficients to fail to achieve the control and adjustment effect of the system to be controlled. to the desired effect
