When the difference that the difference d is more than between threshold value and/or difference d and difference e is more than threshold value, prediction model Z weights Newly take in Tn-Tn-fInput value and the output valve fitting at moment, by threshold decision prediction model Z in Accurate Prediction, when anticipating It is outer to disturb or when reason prediction model Z is inaccurate, original prediction model Z can be directly abandoned, is fitted again.
The input value A sets weight number k, prediction model Z to calculate T after input value * A are fittednThe output at moment Difference g between value and actual value, prediction model Z are calculated in T after input value * A are fittednThe output valve and actual value at moment Between difference h, as g >=h, new weight number will be arranged to, as g ＜ h, new weight number will be arranged to；It must similarly weigh Tuple k can be separately positioned in any input value, and since mechanism model has obvious physical significance, but model is simpler Change, precision of prediction is not often high, although and clear data driving modeling has of a relatively high capability of fitting, no obvious physics Meaning, gained model do not have interpretation, and extrapolation generalization ability is limited, based on above reason, by based on qualitative mechanism Data drive control strategy.The detailed mechanism process of process is not required, it is only necessary to the input/output variable of process is done qualitative Analysis, obtains the pair relationhip between primary variables, by adjusting the weight between input variable, increases the weight of primary variables Coefficient, weakens the influence of secondary variable or disturbance variable, so as to accelerate controller convergence rate, improves the precision of prediction model Z.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation Example, all technical solutions belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications It should be regarded as protection scope of the present invention.
