S22, under said stable chlorination state, obtain pairing chlorination control value under the various operating modes by fuzzy control strategy, and will said various operating modes and corresponding chlorination control value and deposit primary database in.
Schematic diagram referring to fuzzy control strategy shown in Figure 3; The process that realizes fuzzy control strategy simply is described below: microcomputer interrupts the exact value that controlled variable is obtained in sampling; Then this amount is relatively obtained error signal E with set-point, generally select the input quantity of error signal E as fuzzy control.Carry out obfuscation to the accurate amount of error signal E and become fuzzy quantity.The fuzzy quantity of error E can be represented with corresponding fuzzy language, obtains a sub-set e of the fuzzy language set of error E, carries out fuzzy decision by e and fuzzy control rule R composition rule by inference again, obtains fuzzy control quantity u.
Describe in detail below.
Fuzzy control strategy specifically comprises following substep:
A3, confirm input quantity and output quantity;
The control law of general fuzzy control strategy is that the experience of summing up expert or operating personnel gets; So when definite input quantity, output quantity; Mainly observed which amount when fully taking into account their control of expert or on-the-spot experienced operating personnel; That is, as the control foundation, which amount to output to the Be Controlled object through again with the variation of which amount.
In water factory's chlorination system, judge that the leading indicator of chlorination controlled quentity controlled variable is exactly the value of chlorine residue.Chlorine residue conformance with standard (error is in allowed band) explains that then chlorination is suitable, otherwise, be exactly control fails.So judge that the chlorination controlled quentity controlled variable is exactly to carry out according to the size of error, therefore, error is an input variable of fuzzy control strategy strategy, another input variable is exactly an error rate, and it also affects chlorine dosage.Because it has determined error change trend.Thus, it is error and error rate that present embodiment has designed an input variable, and output variable is the two-dimentional fuzzy control strategy strategy of chlorination controlled quentity controlled variable.
By Fig. 3, error obtains through sensor measurement, and said error is the poor of chlorine content and setting value, obtains error rate through error of calculation inverse again.
B3, input quantity is carried out Fuzzy processing;
Input quantity in the fuzzy control strategy and output quantity all are accurate amounts, and fuzzy reasoning all carries out to fuzzy quantity, therefore must carry out Fuzzy processing to input quantity.
Carry out the variable obfuscation and will know the basic domain and the fuzzy language value of variable before.Like Fig. 4, described is the domain (representing the actual change scope of variable for this reason) and the fuzzy language value of input variable (error e, error rate EC) and output variable (controlled quentity controlled variable u).Because of requiring the chlorination control accuracy, the owner must in ± 0.1, be [0.1,0.1] so locate the domain of chlorine residue error; The valve opening increment of controlled quentity controlled variable is 2 to the maximum, and the domain of controlled quentity controlled variable is [2,2].The mapping of input and output conversion as follows so: input: [0.1,0.1] → e; Output: it is 3 that quantification gradation is chosen at this in u → [2,2], and then the fuzzy subset of input/output variable is that { NB, NS, ZO, PS, PB} represent { PB (honest), PS (just little), ZO (zero), NS (negative little), NB (negative big) } respectively.If the domain of chlorine residue error, chlorine residue error rate and controlled quentity controlled variable linguistic variable is respectively X, Y, Z, X=Y=Z={-3 then ,-2 ,-1,0,1,2,3}.
Then, obtaining quantizing factor, is example with the error; The domain maximal value of error is 0.1, seven grades of the branches of fuzzy language, and the quantizing factor of error is exactly ke=7/0.1 so; The value of obfuscation is exactly that actual value multiply by this quantizing factor, if be not integer then round.
Referring to Fig. 5, be fuzzy membership function.The subordinate function of traditional fuzzy control strategy generally all is equally distributed, and in fact the subordinate function curve resolution rate of shape point is high, and control sensitivity is also higher; On the contrary, the subordinate function curve shape is more slow, and control characteristic is also more steady; System stability is better; Relative merits are respectively arranged therefore, present embodiment has proposed to choose the subordinate function of non-uniform Distribution, promptly adopts the fuzzy set of low resolution in the bigger zone of error; Adopt the fuzzy set of high-resolution in the less zone of error, when error approaches zero, select high-resolution fuzzy set for use.In order to improve chlorination control accuracy, response speed, chlorine residue is controlled in the scope of regulation like this, membership function adopts following non-uniform Distribution subordinate function.Degree of membership is exactly to be assigned to the value of fuzzy quantity among the fuzzy subset through degree of membership, is used for control law with this and infers.
C3, infer fuzzy output quantity through the fuzzy control strategy rule;
Referring to Fig. 6, be the fuzzy control strategy rule base of being set up, said fuzzy rule base is write as a rule fuzzy relation through expertise, the such fuzzy rule base that forms at last.
1) deviation e＞0, deviation changes e '＜0, in phase place 1.Deviation is for just, and deviation is changed to negative, the ultra assigned direction variation of the output c of system.If e is that PM and e ' are NM, although explain that deviation is bigger, in rapid minimizing, the ultra assigned direction of system output changes fast, if controlled quentity controlled variable is P, then system will overshoot, so control is output as ZO, it is regular as follows:
If?e?is?PM?and?e′isNM?then?u?is?ZO
When the deviation minimizing, as be PS, and deviation variation e ' is NM, explains under little overgauge, the direction of the ultra set-point of the output c of system changes fast, and for the possible overshoot trend of inhibition system, not only controlled quentity controlled variable u is not P but also should be N, and its rule can be
If?e?is?PS?and?e′is?NM?then?u?is?NS
2) deviation e＜0, deviation changes e '＜0, and e * e '＞0 is in phase place 2.System overshoot, and continue to change to deviating from the set-point direction, drawing close set-point as early as possible in order to make the output c of system, the output u of fuzzy control strategy device is that N and absolute value are bigger.For example, when e is NS, e ' is NM, and its control law can be
If?e?is?NS?and?e′isNM?then?u?is?NM
This rule declaration is though deviation is little.But the deviation pace of change is fast, thereby controlled device applies a bigger controlled quentity controlled variable.
3) deviation e＜0, deviation changes e '＞0, and e * e '＜0 is in phase place 3.The output c of system changes to the set-point direction, and very fast if deviation changes when deviation is big in order to prevent unbalance of system, the output c of system changes fast to set-point, and control law can be:
If?e?is?NM?and?e′isPM?then?u?is?ZO
If?e?is?NS?and?e′isPM?then?u?is?PS
4) deviation e＞0, deviation changes e '＞0, and e * e '＞0 is in phase place 4.This situation is the same with 2, and just system's output changes in the opposite direction, and the fuzzy control strategy device provides bigger controlled quentity controlled variable u, and control law can be:
If?e?is?PS?and?e′isPM?then?u?is?PM
If?e?is?PS?and?e′isPS?then?u?is?PM
D2, fuzzy output quantity is carried out defuzzification obtain the chlorination controlled quentity controlled variable.
The fuzzy output quantity that obtains through fuzzy input quantity and control law can not directly apply to real process, also will carry out defuzzification to it.Defuzzification is exactly the Converse solved of obfuscation, and the defuzzification of controlled quentity controlled variable is exactly that fuzzy value multiply by one than the row factor, and the domain maximal value of scale factor controlled quentity controlled variable is removed with fuzzy grade, i.e. ku=2/7.
S23, primary database is added up optimization, and choose typical condition as storing, to set up with reference to the environmentalist storehouse with reference to operating mode;
Said statistics optimization comprises the data in the said primary database is gone heavily, gone wrong operation, and data are handled, so that data adapting is in the memory module of database.Referring to Fig. 7 and Fig. 8, be respectively in the present embodiment elementary environment data base and with reference to the data type of a variable of being stored in the environmentalist storehouse.
S24, obtain the real-time working condition data;
S25, inquiry set up in advance with reference to the environmentalist storehouse, saidly be used to indicate the various information of controlling the corresponding relation of value with reference to floor data and its chlorination with reference to comprising in the environmentalist storehouse.
S26, according to Query Result confirm with said real-time working condition Data Matching with reference to operating mode, with said with reference to the corresponding chlorination controlled quentity controlled variable of operating mode as the first control value;
S27, utilize fuzzy control strategy to said first control value handle, obtain second control value;
S28, the weighted sum of controlling value through the said first control value and second obtain current control value, and carry out chlorination control according to said current control value;
S29, according to control effect said confidence level with reference to stored relation in the environmentalist storehouse is estimated;
Can estimate its confidence level through setting evaluation of estimate, said confidence level just can be with reference to property, in order to the quality of record controls effect.When system initially is written into raw readings,, increase and decrease one according to practical operation situation later on for the evaluation of estimate of the confidence level of every corresponding relation is set to a fixing value.If a certain corresponding relation can be used for control, and can in three control cycles, keep departure in specialized range; We think that this corresponding relation has reference significance; Confidence level adds one, otherwise subtracts one, when the evaluation of estimate of the confidence level of a certain corresponding relation is 0 or when negative; Think that then this corresponding relation does not have reference significance, can be with this corresponding relation deletion.
S210, according to the evaluation of estimate of said confidence level, make amendment and optimize with reference to the environmentalist storehouse said, improve said reference value with reference to the environmentalist storehouse.
This step can be through being provided with online learning functionality in reference to the environment experts database and realizing said.Because chlorination system is can be by the single output system that different operating mode influenced; Its output under the normal condition (being the chlorine dosage set-point) should constitute certain mapping relations with floor data; Wherein dosage is a variations per hour; Relevant with multiple factor, therefore can obtain the approximate value that the ideal corresponding with it adds concentration through on-line study through setting up the form of a chlorinating machine aperture under duty parameters such as difference filter back discharge, the different clear water reserviors water levels content in the environmentalist storehouse as a reference.Be responsible for estimating with reference to the study of environment experts database and adaptive mechanism and add effect (chlorinating machine aperture), realize online correction reference data, rolling optimization, and confirm that in real time suitable chlorinating machine adds aperture and some other controller parameter.Through on-line study, make with reference to the data in the environment experts database to obtain revising and optimizing, improved the control effect greatly.
