The degree of membership of temperature gear, its value are 0-1, so as to be based on the Fig. 3, for the Temperature numerical of a determination, can be passed through
The Temperature numerical is in degree of membership corresponding to each gear, to judge that the gear of the Temperature numerical is subordinate to situation, as shown in figure 3, warm
Angle value Ta, the degree of membership corresponding to low-grade location are a1, and the degree of membership corresponding to relatively low gear is a2.
The board temperature T2 of solid state hard disc temperature gear division and degree of membership distribution situation, the CPU cores with solid state hard disc
Piece temperature T1 temperature gear division and degree of membership distribution situation are consistent, specifically refer to above to the CPU cores of solid state hard disc
The piece temperature T1 division of temperature gear and the introduction of degree of membership distribution situation, here, is no longer described in detail.
Consider that this implementation is specifically examined using the board electric current I of solid state hard disc and board voltage V as during input variable at the same time
The board power consumption P=V*I that to be calculated based on board electric current I and board voltage V is considered, as board electric current I and board can be embodied
Voltage V generalized variable is as input.Wherein, power consumption range of the present embodiment based on empirical hypothesis board is 12W-20W, and will
The power consumption range of the 12W-20W is divided into third gear：Normally, it is high, it is higher.Simultaneously establish the input variable i.e. board power consumption this
The membership function of variable, degree of membership distribution percentage specifically refers to Fig. 4, in Fig. 4, transverse axis corresponding to the membership function
Power consumption is represented, its span is 12W-20W, and the longitudinal axis represents that power consumption numerical value corresponds to the degree of membership of corresponding power consumption gear, and it takes
It is worth for 0-1,, can be by the power consumption numerical value in each gear pair for the power consumption numerical value that one determines so as to be based on the Fig. 4
The degree of membership answered, to judge that the gear of the power consumption numerical value is subordinate to situation, as shown in figure 4, power consumption number Pb, corresponding to normal gear

(2) output variable：
The input and output speed such as IOPS of solid state hard disc is arranged to output variable, it is assumed that solid state hard disc board IOPS reason
It is [0-150] K/s by scope, then is divided into 5 IOPS gears：Stop, be very low, low, lower slightly and do not control, when IOPS is
When 0, it is believed that data read-write operation stops completely, accordingly, will so as to which IOPS values corresponding to described " stopping " gear are 0
IOPS values corresponding to " not controlling " gear are arranged to 0, wherein it is desired to which explanation, described " very low " this gear do not wrap
The value that IOPS is 0 is included, described " lower slightly " this gear does not include the value that IOPS is 150.And establish the person in servitude of the output variable
Category degree function, degree of membership distribution percentage specifically refers to Fig. 5 corresponding to the membership function.

It is low " degree of membership of gear is c1, the degree of membership corresponding to " low " gear is c2.
On this basis, the fuzzy rule that the present embodiment is established is as shown in table 1 below：
Table 1
For above-mentioned table 1, specifically, when chip temperature T1 is height, board temperature T2 is higher, when power is normal,
Then solid state hard disc temperature is very high, even if now solid state hard disc is normal, then still controls IOPS to stop, that is, make it that solid-state is hard
Disk stops input and output, and the high temperature protection purpose to solid state hard disc is reached with this；When chip temperature T1 is low, board temperature T2 is
Low, power is height, even if now power is very high, is also not required to apply limitation for IOPS；When chip temperature T1 is medium, board temperature
T2 is spent to be medium, and power is height, then can somewhat control the IOPS of solid state hard disc to be lower slightly.And what above-mentioned table 1 provided obscures
The explanation of 3 entries of other respective entries and the above in rule is similar, no longer describes one by one.

Degree of membership, and the fuzzy rule shown by based on table 1, determine target input and output speed gear that the disk need to use and right
Should be in the 4th degree of membership of the target input and output speed gear.
Here, it is necessary to which explanation, the first temperature gear, second temperature gear etc. are only that and show chip temperature respectively
The gear that degree, board temperature are subordinate to respectively, and in some cases, a certain specific chip temperature value or board temperature value can
More than one temperature gear can be under the jurisdiction of, temperature value Ta as shown in Figure 3 is under the jurisdiction of " normal " gear and " higher " gear
The two gears, it is corresponding so as to which the first temperature gear can include " normal " gear and " higher " gear
Ground, the degree of membership that the numerical value that first degree of membership can then include corresponding respectively to described " normal " gear is a1, and it is right
The numerical value of " higher " gear described in Ying Yu is a2 degree of membership.Other gears and degree of membership, such as described second temperature gear, the
