Abstract
The invention discloses a composite type predictive control algorithm applied to automatic matching in a carbon plant. According to the algorithm, characteristics of rapid fuzzy control width range adjustment and precise PID (Proportion Integration Differentiation) adjustment are organically combined, when the deviation of a system is greater than one set value, fuzzy rule control with the combination of human experience is adopted, and when the deviation of the system is smaller than the set value, PID control is adopted. Two input values of a fuzzy controller are respectively an expected system value and the deviation, and different falls in all can be predicted through different expected values. The algorithm has the advantages that practical application shows that the precision and the velocity of the system are both improved by using the algorithm when being compared with that of single PID control, the contradiction of matching velocity and matching precision is solved, and the pass percent of a product is increased.
Description
technical field:
The invention belongs to electronics industry, particularly
a kind of compound predictive control algorithm of applying in carbon element factory's automatic blending.
background technology:
Automatic blending algorithm in the past, can not solve the contradiction between proportioning accuracy and batching speed, in the situation that emphasizing proportioning accuracy, will increase the batching time; Vice versa.
summary of the invention:
The technology of the present invention originating party case: produce the unmanageable problem of proportioning accuracy in automatic blending process for carbon product, proposed the compound predictive control algorithm of a kind of fuzzy combination PID.Algorithm combines the feature of fuzzy control wide region quick adjustment and PID fine adjustment, adopts the fuzzy if-then rules of the experience that combines people when the deviation of system is greater than a certain setting value, adopts PID to control when system deviation is less than setting value.Two inputs of fuzzy controller are respectively system expectation value and deviation, by different expectation values, predict different aerial drops.
Advantage of the present invention: practical application shows that this algorithm is controlled in system accuracy and speed and all increases than simple PID., solved this contradiction of batching speed and proportioning accuracy, improve product percent of pass.
embodiment:
For carbon product, produce the unmanageable problem of proportioning accuracy in automatic blending process, proposed the compound predictive control algorithm of a kind of fuzzy combination PID.Algorithm combines the feature of fuzzy control wide region quick adjustment and PID fine adjustment, adopts the fuzzy if-then rules of the experience that combines people when the deviation of system is greater than a certain setting value, adopts PID to control when system deviation is less than setting value.Two inputs of fuzzy controller are respectively system expectation value and deviation, by different expectation values, predict different aerial drops.
