Introduce 91 pairs of associating heaters of computer control system of the present invention 11 below and carry out the fuzzy control method that temperature control is adopted.It is realized with fuzzy control rule or fuzzy control matrix.Suppose that A, B, C are fuzzy quantity.For temperature controlled fuzzy quantity, there are three kinds: temperature error, temperature error rate of change and controlled quentity controlled variable.Temperature error represents with e, and it is the poor of the temperature value Y that measured of temperature given value R and Temperature Detector 18, i.e. e=R-Y.
Temperature error is got 8 fuzzy values, and they are respectively negative big NB, negative middle NM, negative little NS, negative zero NZ, positive zero PN, just little PS, center PM, honest PB.The definition of these fuzzy values is determined by test according to the requirement of the process of cooking of various dish.Clearly NB, NM, NS, NZ etc. are fuzzy values, rather than exact value, because each fuzzy value all within limits, the fuzzy value of e is represented with A.The temperature error rate of change represents that with △ e it is the difference of adjacent twice temperature error values.Be △ e=e(TC)-e(TC-1), TC represents current time in the formula, the fuzzy value of △ e is represented with B.Error rate is got 7 fuzzy values, and they are respectively negative big NB, negative middle NM, negative little NS, 00, just little PS, center PM, honest PB.The definition of the fuzzy value of error rate is determined by test.
Controlled quentity controlled variable represents that with C it also gets 7 fuzzy values, and its form and error rate are similar.
After the fuzzy value that has defined temperature error A, temperature error rate of change B and controlled quentity controlled variable C,, when controlling, temperature uses statement according to people's experience:
If A and B then C
Expression, its concrete reasoning statement is following composition statement:
If A＝NB and B＝NS then C＝PB
If A＝NS and B＝0 then C＝PS
……
Represent all control laws with a general formula:
If A（i） and B（j） then C（i，j）
In the formula, i=1～m, j=1～n
According to each reasoning statement in the control law, then can obtain fuzzy relation
:
In the formula, " * " expression operation of direct product.Operation of direct product is defined as follows formula:
In the formula: ∨ represents or operates,
∧ represent with the operation,
μ () represents membership function.
After having obtained fuzzy relation R, then, can obtain controlled quentity controlled variable C for any real-time temperature error A and temperature error rate of change B.
In the formula: " * " expression operation of direct product,
"
" the expression compose operation.
In formula (1-1), compose operation is defined as follows: for fuzzy relation
, have
For
With
Compositive relation, and:
And
Then can obtain fuzzy control quantity C according to compose operation definition and formula (1-1).
Owing to must adopt exact value when associating heater 11 is carried out temperature control, so fuzzy control quantity C need carry out precision.The method of carrying out the fuzzy quantity precision has: maximum membership degree method, median method, weighted mean method etc.The present invention adopts the maximum membership degree method, and fuzzy control quantity C is transformed into after the accurate amount, just can remove to control the heating current that feeds in the associating heater 11.
In working control, generally not to go to carry out synthetic with fuzzy relation and obtain fuzzy control quantity C's with Real-time Error and error rate.Because used time of compose operation is longer, computing is comparatively complicated, so the present invention takes in all possible input condition, what computer precomputed correspondence may export situation, so just can under the condition of off line, produce a control table, this control table has two input quantities, and promptly temperature error A and temperature error rate of change B have an output quantity, be controlled quentity controlled variable C, at any time, know the value of A, B, just can from control table, find corresponding controlled quentity controlled variable C.In sum, compose operation has just become the foolproof computing of tabling look-up in the present invention.
