Be preset with temperature reference signal in main control terminal 2, main control terminal 2 receive current temperature detection signal and with temperature reference signal
It compares and passes through fuzzy algorithmic approach and calculate corresponding output frequency to driver 5.
Fuzzy algorithmic approach is realized in the following manner:
P1, selection observed quantity and control amount；
It is typically chosen deviation e, i.e. target fiducials temperature and the difference of Current Temperatures selects output frequency u for control as observed quantity
Amount.
The blurring of P2, input quantity and output quantity；
Deviation e is divided into 5 fuzzy sets, negative big (NB), bears small (NS), zero (ZO), just small (PS), honest (PB), e is negative table
Show Current Temperatures lower than target water level, e, which is positive, indicates that Current Temperatures are higher than target temperature.The value range of e is set as [- 3,3],
Subordinating degree function is as shown in figure 4, the corresponding fuzzy table of deviation e is as shown in Figure 5.

(1) if e is negative big, u is negative big；
(2) if e bears small, u bears small；
(3) if e is zero, u zero；
(4) if e is just small, u is just small；
(5) if e is honest, u is honest；
" IF A THEN B " is converted by the above-mentioned rule to describe in words.
P4, fuzzy relation is solved；
Fuzzy relation set R can be obtained by corresponding fuzzy set operation according to the fuzzy rule of formulation.
And rule is as follows:
1.IF NBe THEN NBu；
2.IF NSe THEN NSu；
3.IF ZOe THEN ZOu；
4.IF PSe THEN PSu；
5.IF PBe THEN PBu。
P5, fuzzy decision is carried out；
The control amount u finally obtained is the output of fuzzy control, and u can be synthesized by deviation matrix e and fuzzy relationship matrix r
It arrives.
That is, u=eR
The anti fuzzy method of P6, control amount；
The control amount u that fuzzy decision obtains is a matrix, it is therefore desirable to which u is construed to specific behavior in practice, i.e. reverse
Gelatinization operation.
Currently used anti fuzzy method method has following several:
(1) maximum membership degree method；
(2) gravity model appoach；
(3) weighted mean method.
P7, matlab are realized；
The operation of P4-P6 step solution matrix operation can be directly realized in matlab fuzzy logic toolbox, it is only necessary to straight
It connects and evalfis function is called to can be obtained by corresponding Decision Control amount.
The fuzzy control model integrated by matlab, obtains the relationship for answering deviation e and control amount u, and adjustable e exists
The corresponding output of u under different value.

When rotation detection signal, driver 5 keeps currently exporting, to realize holding current rotating speed；When rotary speed data, torque data are less than
When rotation detection signal, driver 5 increases output, to realize speed-raising.
Module 18 is overhauled simultaneously for judging whether driver 5 is slowed down or raised speed, when speed has been corrected, no
It sends in corresponding information to corresponding cell-phone number；When speed is not corrected, corresponding information is sent to corresponding cell-phone number
On.And judging whether that modified standard is, the difference of rotary speed data, torque data and rotation detection signal whether there is.
