Description
Technical field
The present invention relates to the fuzzy control technology field, be specifically related to a kind of human intuition reasoning type fuzzy controller based on conventional logical device.
Background technology
As everyone knows, fuzzy controller is a kind of intelligent controller based on language rule, now be applied to various industrial process controls and tame electric control field, but The Design of Fuzzy Logic Controller has higher technical threshold to the deviser, thereby limited it and further applied.Since the generation of fuzzy controller, people use its most direct power and come from: there are many successful manually-operated experiences some production scenes, these experiences can be write as IF-THEN language rule form, and people wish to utilize control device to duplicate the control behavior of human brain.But human language has ambiguity, and control device all is based on concrete numerical value, and this becomes the obstacle of the control behavior maximum of duplicating human brain.The appearance of fuzzy mathematics, people have expected utilizing Fuzzy Set Theory to handle the problem of language rule naturally.For example, people generally believe: the approximate range of car speed " very fast " is 80km/s～150km/s, the approximate range of car speed " fast slightly " is 60～90km/s, the actual travel speed 84km/s of existing certain automobile, does the speed of this automobile belong to " very fast " and still belongs to " fast slightly " so? obviously, two fuzzy sets " very fast " are overlapped with " fast slightly " existence.Just because of human language is to allow this overlapping existence,, both be said to " very fast " so different people has different answers, also be said to " fast slightly ".A kind of effective handling implement is exactly a membership function.For example, by the predefined membership function, the membership values that the speed of our desirable this automobile belongs to " very fast " is 0.4, and the membership values that belongs to " fast slightly " is 0.6.In other words, concrete numerical value lotus root simultaneously closes 2 (or more than) fuzzy sets, can activate many language rules simultaneously thus.This just requires us must consider " synthesizing " (comprehensively) reasoning problems of rule when controller is stuck with paste in design.At present, the fuzzy controller product all is based on " synthesizing " reasoning.But many frontline engineers use with safeguarding difficult and abandon because of " synthesizing " the reasoning indigestion to fuzzy set.Therefore, in some occasions, what people needed is a kind of being easy to learn and use and fuzzy controller reliable for effect.
By analysis, we find that above-mentioned " synthesizing " reasoning and execute-in-place person's working control method is inconsistent.For example the operator of certain model boiler has summed up following two control laws through long-term work: rule 1: temperature is low slightly, then increases fuel and supplies with 10%; Rule 2: temperature is suitable, and it is constant then to keep fuel to supply with.For this model boiler, the operator generally believes that the approximate range of " temperature is low slightly " is 80～95 ℃, and the approximate range of " temperature is suitable " is 90～100 ℃.If temperature instrument shows that Current Temperatures is 92 ℃, the operator of this moment must make judgement intuitively rapidly, or uses the 1st rule, or uses the 2nd rule, and needn't consider the fuzzy reasoning method of abstract complexity.The criterion of supposing him is: the scope of " temperature is low slightly " is 80～92.5 ℃, and the scope of " temperature is suitable " is 92.6～100 ℃.At this moment, the operator can use the 1st rule naturally.This judgement is finished intuitively the operator, and we select for use this judgement intuitively the method for fuzzy rule to be referred to as the intuition rationalistic method.Obviously, this intuition rationalistic method comes down to utilize experienced operator's intuition to judge that the lotus root of removing between the fuzzy set closes relation, makes it the new method of only using a fuzzy rule to export.It is different with the T-S method with traditional Mamdani method, and it is a kind of reasoning process of complete apery.If this intuition rationalistic method is applied to then be referred to as human intuition reasoning type fuzzy controller in the fuzzy control apparatus.This human intuition reasoning type fuzzy controller has directly simple, is easy to learn and use, and is particularly suitable for not learning frontline engineer's use of fuzzy mathematics.Simultaneously, it is again the direct application of operator's successful experience, is actually the control behavior that utilizes fuzzy control device replicate run person, beyond doubt effectively reliably.
At present, the hardware way of realization of fuzzy controller has two kinds:
1. based on the control circuit of CPU and storer, inference method is write as the burned storage chip of programmed instruction, the advantage of this form is that software programming is flexible, and shortcoming is that processing speed is slower, poor stability.
2. based on the control circuit of storer, in advance the mapping relations of all inputoutput datas are directly deposited in storage chip, the advantage of this form is that processing speed is very fast relatively, and shortcoming is that dirigibility is relatively poor.
Both common drawback are, all need use abstract fuzzy reasoning method hard to understand, are difficult to study and use, and this has constituted challenge to many frontline engineers, has restricted the popularization and the application of fuzzy controller.

Now lift concrete numerical value (temperature deviation e=0.5V, temperature deviation rate of change ec=2.8V) course of work of the present invention is described.According to the human intuition reasoning method, at first temperature deviation e=0.5V should be belonged to a fuzzy set, temperature deviation rate of change ec=2.8V is also belonged to a fuzzy set, the output result according to comparer selects default value and output then.At these data, the concrete course of work of the present invention is as follows:
The 1st step: after the analog temperature deviation signal of outside input e=0.5V,, under the cooperation of clock CLK, lock in first latch 12 through obtaining digital deflection data 19H after 11 conversions of first analog to digital converter.Obtain the deviation of simulation rate of change signal of ec=2.8V through differentiator 13 when the temperature error signal of outside input e=0.5V, through the digital deflection rate of change data 8EH that obtains after 14 conversions of second analog to digital converter, similarly, under the cooperation of clock CLK, lock in second latch 15.
The 2nd step: after 5 first comparers (COMP1, COMP2, COMP3, COMP4, COMP5) of the data 19H of deviation signal and deviation data passage 3 compare, according to Fig. 4 as can be known 19H drop in the corresponding fuzzy set of the first comparator C OMP1, therefore the lead-out terminal E1 that has the first comparator C OMP1 only is high level " 1 ", and the output of all the other 4 comparers is " 0 ".After 5 second comparers (COMP6, COMP7, COMP8, COMP9, COMP10) of the data A3H of deviation variation rate signal and deviation variation rate data channel 4 compare, according to Fig. 5 as can be known A3H drop in the corresponding fuzzy set of the second comparator C OMP9, the lead-out terminal EC4 that has the second comparator C OMP9 only is high level " 1 ", and the output of all the other 4 comparers is " 0 ".
The 3rd step: under the effect of two gating signals of lead-out terminal EC4 of the lead-out terminal E1 of the first comparator C OMP1 and the second comparator C OMP9, connect with the three-state buffer unit that back three-state buffer S29 is formed by preceding three-state buffer S4, be that terminal Z4 and the 3rd latch 61 are connected, remaining three-state buffer unit all is high-impedance state.

PSLink to each other with Z4.Therefore the output terminal Z of the value storage of preset data PS (CCH) is connected in the three-state buffer unit of being made up of preceding three-state buffer S4 and back three-state buffer S29
PSThereby preset data CCH locks under the cooperation of clock CLK in the 3rd latch 61 through behind this three-state buffer unit.
The 5th step: the data CCH of the 3rd latch 61 outputs is output aanalogvoltage 4.0V after digital to analog converter 62 conversions, and this voltage is the final output quantity of the human intuition reasoning type fuzzy controller in the present embodiment.
