Requirement based on brewage process process to temperature stability and accuracy, and consider the cost performance of system, therefore Select two-dimensional fuzzy controller.The design of typical two-dimensional fuzzy controller generally includes following four step:
Step 1:Blurring determines the assignment table of fuzzy variable using normal distribution, by temperature error and error change amount Precise volume be converted to fuzzy quantity.
Step 2:Fuzzy reasoning carries out fuzzy reasoning according to IF-THEN language rules, system whole fuzzy relation institute is obtained Corresponding control rule is placed in rule base.
Step 3:Fuzzy judgment obtains the fuzzy of control parameter with the methods of maximum membership degree method, weighting average decision method Amount.
Step 4:De-fuzzy is transformed into the result after fuzzy judgment by fuzzy quantity the essence that can be used for actually controlling Really amount.
Such fuzzy controller is applied in temperature control system, forms a closed-loop control system.Controller will be adopted The temperature collected obtains temperature error e compared with setting value, and passes through differentiation element and obtain the variable quantity ec of temperature error. And to e and ec, this two groups of data carry out Fuzzy processings, determine its degree of membership, so as to obtain the input quantity E of fuzzy reasoning and EC.It is offline to formulate controlled quentity controlled variable inquiry table according to the experience of brewage process.The table is stored in rule with the rule format of IF-THEN In library, for being inquired in the fuzzy reasoning process during system operation.The obtained output quantity of reasoning is sentenced with weighted average Certainly method carries out fuzzy judgment, so as to obtain corresponding control parameter.The processing of de-fuzzy is carried out to this control parameter, so as to The exact value for actually controlling is obtained, and for the pulse width for controlling solid-state relay folding is adjusted, so as to make For temperature execution part.This temperature is acquired simultaneously by temperature sensor again, to carry out the temperature of next cycle Monitoring and control.
Fuzzy control is carried out, must just Fuzzy processing be carried out to input variable, non-Defuzzication is carried out to output variable Processing.If the quantification gradation of the variable quantity ec and output controlled quentity controlled variable U of temperature error e, temperature error are all 13 grades, domain is all { -6, -5, -4, -3, -2, -1,0,1,2,3,4,5,6 }, fuzzy language collection is divided into seven grades, is denoted as NB (negative big), NM (in negative), NS (negative small), Z (zero), PS (just small), PM (center), PB (honest).It is to set to select appropriate input, output fuzzy membership function The key of fuzzy controller is counted, from stability, the input fuzzy set membership function of temperature error selects continuous type Gauss Type function.

With reference to the characteristics of tin stove warming operation experience and temperature variable, the design principle of the fuzzy control rule of this temperature control system is:When When error is larger, controlled quentity controlled variable should reduce error as much as possible;When error is smaller, other than eliminating error, it is also contemplated that arrive The stability of system vibrates to avoid the hyperharmonic of undesirable appearance.By taking temperature error is negative big (NB) as an example, when error Variation also for negative (NB, NM or NS) or equal to zero when, control should eliminate error as early as possible, increase controlled quentity controlled variable, thus should select PB for Controlled quentity controlled variable;And the variation of error is timing, should reduce the variation of controlled quentity controlled variable.Therefore the control rule table of fuzzy controller is summed up As shown in table 1.
1 fuzzy control rule table of table
According to the control of table 1 rule, fuzzy reasoning is carried out by formula (1), (2):
μ·Rk(U)=min { μ Ei(E),μEcj(Ec),μUk(U)} (1)
μ·Rk(U)=max { μ Rk(U)} (2)
By fuzzy reasoning obtain the result is that a fuzzy set, but in fuzzy control, it is necessary to which there are one determine Value could drive executing agency.Taken in the fuzzy set obtained in reasoning one can most preferably represent this fuzzy reasoning result can The process of the exact value of energy property claims non-Defuzzication process, has smoother output reasoning and decision using weighting average decision method, Correspond to that certain variation can also occur for the final output of input signal minor change its reasoning and this variation is smoother.
Then with the weighting average decision method shown in formula (3), sharpening is carried out to each fuzzy subset R, obtains and corresponds to The U of every group of E, EC, and rounding optimization is carried out to calculated value, so as to show that fuzzy control table is as shown in table 2.
