Interior force value is positioned at standard area；
By not setting up linear model, directly by the way of data matching, set up prediction by organizing input value and output valve more
Model Z, i.e. greatly reduces the requirement to model priori, is especially suitable for controlling the refine furnace pressure of unknown-model
The optimal control of journey, and due to force value [B in pressure A and reverberatory furnace 2 in combustion furnace 11-Bm] exist due to course of reaction always
In random nonlinear change, and due in combustion furnace 1 and reverberatory furnace 2 pressure change make convulsion assembly and valve member 5
Actual motion has certain random deviation in expectation operation, possesses steady-state error, by many groups of direct matching input the most always
Set up forecast model Z between value and output valve and be avoided that the steady-state error impact on control accuracy, make combustion furnace 1 interior and reverberatory furnace
In in 2, pressure maintains accurate scope.
Described step S2 is further comprising the steps of: TnTime inscribe forecast model Z by Tn-c-TnA, [B in moment1-Bm]、X、
[Y1-Ym] numerical value obtains, c is more than zero and be natural number, i.e. passes through to take the c group input value that always updating, output valve is that matching is pre-
Survey the numerical value of model Z, i.e. can update forecast model Z always, and forecast model Z can be made more accurately based on up-to-date data
Prediction situation instantly.
Described step S2 is further comprising the steps of: as A, [B1-Bm]、X、[Y1-YmIn], the rate of change of any one is high
When threshold value, reduce TnWith Tn-1Between time interval, as A, [B1-Bm]、X、[Y1-Ym] rate of change when being respectively less than threshold value,
Increase TnWith Tn-1Between time interval, TnWith Tn-1Between time interval be provided with maximum and minima, pass through input value
Rate of change can speculate the rate of change of realistic model, when the rate of change of model is higher than threshold value, reduce the sampling interval, Fast Fitting
Forecast model Z, makes forecast model Z can catch up with the rate of change of realistic model, the prediction essence of a certain degree of reinforcement forecast model Z
Degree, when the rate of change of model is less than threshold value, increases sampling interval, accurate matching forecast model Z, makes forecast model Z more accord with
Close realistic model, strengthen the precision of prediction of forecast model Z.
Described step S2 is further comprising the steps of: calculate forecast model Z at Tn+1Between output valve and the actual value in moment
Difference d, it was predicted that model Z is at matching TnCalculate at T after the input value in moment and actual valuen+1The output valve in moment is with actual
Difference e between value, as e >=d, not by TnThe input value in moment and actual value are updated in forecast model Z, as e ＜ d,
By TnThe input value in moment and actual value are updated in forecast model Z, i.e. by after comparing renewal or not updating in the case of
The precision of forecast model Z judges whether to update, i.e. by judging whether new identification model can improve one-step prediction error
Decide whether the control strategy of more new model, considerably increase the precision of forecast model Z.
When described difference d is more than threshold value more than the difference between threshold value and/or difference d and difference e, it was predicted that model Z weight
Newly it is taken at Tn-Tn-fThe input value in moment and output valve matching, by threshold decision forecast model Z at Accurate Prediction, when meaning occur
Outer interference or etc. reason forecast model Z inaccuracy time, can directly abandon original forecast model Z, again matching.
Described input value A arranges weight number k, it was predicted that model Z calculates T after matching input value * AnThe output in moment
Difference g between value and actual value, it was predicted that model Z calculates at T after matching input value * AnThe output valve in moment and actual value
Between difference h, as g >=h, new weight number will be set to, as g ＜ h, new weight number will be set to；In like manner must weigh
Tuple k can be separately positioned in any input value, and owing to mechanism model has obvious physical significance, but model is simpler
Change, it was predicted that precision is the highest, although and clear data drive modeling have of a relatively high capability of fitting, but there is no obvious physics
Meaning, gained model does not have interpretability, and extrapolation generalization ability is limited, based on above reason, by based on qualitative mechanism
Data drive control strategy.I.e. need not the detailed mechanism process of process, it is only necessary to do qualitative to the input/output variable of process
Analyze, obtain the pair relationhip between major variable, by the weight between regulation input variable, strengthen the weight of major variable
Coefficient, weakens secondary variable or the impact of disturbance variable, thus accelerates controller convergence rate, improves the precision of forecast 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 enforcement
Example, all technical schemes 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 are also
Should be regarded as protection scope of the present invention.
