S223, the raising frequency speed that gravity model appoach calculating compressor is passed through according to degree of membership and fuzzy control table.
Specifically, according to the outdoor environment temperature and compressor current collected, determined using FUZZY ALGORITHMS FOR CONTROL
The speed of compressor raising frequency, using N as 7, it is illustrated below：Outdoor environment temperature is divided into ultralow, relatively low, low, normal,
High, higher, superelevation } totally 7 temperature ranges；Compressor current is divided into { extra small, smaller, small, normal, big, larger, super large }
Totally 7 electric current sections；Compressor raising frequency speed is divided into it is super it is slow, relatively slow, at a slow speed, it is positive constant speed, quick, very fast, ultrafast totally 7
Individual raising frequency section；Each temperature range, electric current section and raising frequency section are corresponding in turn to are digitized as -3, -2, -1,0,
1,2,3 }；According to each temperature range after digitlization, electric current section and raising frequency section, fuzzy control table corresponding to composition.
Outdoor environment temperature is divided into { ultralow, relatively low, low, normal, high, higher, superelevation }, because refrigeration and heating temperature
It is different to spend section, it is therefore desirable to gear is respectively divided for the temperature range freezed and heated；For example, it is ultralow for 10 ~
14 DEG C, relatively low is 14 ~ 18 DEG C, and low is 18 ~ 22 DEG C, is from temperature from low to high each on ultralow, relatively low, low
The descriptor of temperature range, scope can be configured as needed corresponding to each descriptor.Compressor current is also made similar
Division, such as { extra small, smaller, small, normal, big, larger, super large }；For example, extra small is 100 ~ 200mA, it is smaller be 200 ~
300mA, etc.；It is descriptor, each description corresponding to each electric current section of electric current from small to large on extra small, smaller, small etc.
Scope corresponding to word can be configured as needed.Compressor raising frequency speed is also divided into { super slow, more slowly, at a slow speed, normally
It is fast, quick, very fast, ultrafast }；For example, it is super it is slow be 0 ~ 1Hz/s, relatively slowly for 1 ~ 2 Hz/s etc.；On super slow, relatively slow, at a slow speed
Deng, be compressor raising frequency speed to descriptor corresponding to fast each raising frequency section, scope corresponding to each descriptor can slowly
It is configured as needed.Above demarcation interval can be digitized as { -3, -2, -1,0,1,2,3 } respectively.For example, phase
Accordingly, above-mentioned ultralow, extra small, super slow correspondence -3；It is relatively low, smaller, relatively slow then to correspond to -2, by that analogy.Then basis is adopted
Gear section where the gentle compressor current of actual rings collected determines raising frequency speed stage using fuzzy decision mechanism.When
So, corresponding frequency reducing also can using the present invention raising frequency method it is anti-come.
Referring to Fig. 2, as shown in Fig. 2 outdoor environment temperature is divided into { ultralow, relatively low, low, normal, high, higher, super
It is high } totally 7 temperature ranges, the matching degree of empirically determined each environment temperature and these temperature ranges, so as to obtain
The graph of a relation of temperature and degree of membership, T1 ~ T7 are respectively the temperature spot that this 7 temperature range degrees of membership are 1, that is to say, that T1 ~ T7
For the separation of above-mentioned 7 temperature ranges, for example relatively low is 14 ~ 18 DEG C, then it 14 and 18,14 is relatively low boundary that separation, which is,
Point, and 18 are low separation, then when environment temperature is 16 DEG C, corresponding and relatively low degree of membership is 0.5；With low person in servitude
Category degree is 0.5.Similarly, the degree of membership graph of a relation of compressor current can be obtained according to identical method, as shown in Figure 3；I1~I7

Degree.Numeral corresponds to the corresponding gear of division in table, such as compressor current I：- 3 represent extra small, and -2 represent smaller, -1
Represent small, 0 represents normal, and 1 represents big, and 2 represent larger, and 3 represent super large.
Then, outdoor environment temperature and compressor current are blurred（Temperature and electric current are divided into different sections, obtained
The Degree of Accord Relation that is consistent to different temperatures and electric current with section, i.e. degree of membership）；Then the fuzzy of correlation is obtained according to practical experience
Control rule table；It is finally fuzzy decision：According to the blurring data of obtained input quantity and fuzzy control rule table according to weight
