Sequence, and when computer program is executed by processor realize each step of above-mentioned air conditioner electronic expansion valve adjusting method.
Air conditioner electronic expansion valve adjusting method embodiment：
Referring to Fig. 2, the air conditioner electronic expansion valve adjusting method of the present embodiment carry out to be tested the electric expansion valve 30 of air-conditioning into
When row is adjusted, step S1 is first carried out, judges whether the compressor 20 of tested air-conditioning is in running order, if it is judged that being
It is no, then continue to execute step S1, if it is determined that the compressor 20 of tested air-conditioning is in running order, then step S2 is performed, pre-
If obtaining the data of multiple actual exhaust air temperature values in the time, and the data of rate are generated according to multiple actual exhaust air temperature values.
Wherein, the data of rate are the speed data of actual exhaust air temperature change, when the compressor 30 for determining tested air-conditioning is in work
It, can be practical within a certain period of time to calculate by PID regulator 10 come the multiple actual exhaust air temperature values of timing sampling during state
The rate of exhaust gas temperature change, and can be obscured according to the rate and the difference of actual exhaust air temperature and target exhaust temperature
Reasoning.For example, after determining that compressor 20 is in running order, the data of the first actual exhaust air temperature value are obtained, and judgement is
It is no to reach the time for obtaining actual exhaust air temperature value next time, if so, then obtaining the data of the second actual exhaust air temperature value, and root
The data of rate are generated according to the first actual exhaust air temperature value and the second actual exhaust air temperature value.
Certainly, it in order to improve the Accuracy and high efficiency of detection, needs by whether reaching the preset testing time to sentence
Whether the compressor 20 of disconnected tested air-conditioning meets the condition opened and obtain actual exhaust air temperature Value Data next time, if for example, pre-
If testing time be 10 seconds, begun to while PID regulator 10 obtains outlet air temperature for the first time start timing mode,
And judged whether to reach the preset testing time according to the startup time, that is, whether reached 10 seconds, if so, can determine
Compressor 20 meets the condition opened and obtain actual exhaust air temperature Value Data next time.
Specifically, the preset testing time can be by user according to practical application sets itself, user can be according to specific
The runnability of use environment and tested air-conditioning is set, setting for the testing time, the test in above-described embodiment
Time is set as 10 seconds, may be set to be 5 seconds, 15 seconds, other numerical value such as 20 seconds.It can obtain pressure according in actual use
The parameter settings such as the efficiency or tested air-conditioning internal controller processing speed of 20 actual exhaust air temperature of contracting machine.
Then, step S3 is performed, compares actual exhaust air temperature value and target exhaust temperature value, and generate according to comparison result
Difference.Wherein, difference is actual exhaust air temperature value and the difference of target exhaust temperature value, since outlet air temperature is by certain factors
Different variations can occur for influence, such as suction temperature, motor heat or compression ratio is excessively high.
Then, step S4 is performed, fuzzy reasoning is carried out, and result generates fuzzy quantity by inference according to difference and rate.
In the present embodiment, PID regulator 10 can be fuzzy controller, and fuzzy controller is by conventional PID controllers and mould
Module composition is gelatinized, fuzzy controller can be obtained between three parameters of pid control algorithm and above-mentioned difference and rate
Fuzzy relation constantly detects difference and rate, and three parameters is carried out according to determining fuzzy control rule in operation
On-line tuning meets different differences and rate and three the different of parameter is required.Wherein, above three parameter is PID controls respectively
Proportionality coefficient, integral coefficient and the differential coefficient of algorithm processed.
Specifically, fuzzy control theory is built upon on the basis of fuzzy set theory, Fuzzy Linguistic Variable and fuzzy logic inference
A kind of computer numerical control (CNC) it is theoretical, membership function is the application foundation of fuzzy control, first during fuzzy reasoning
First, it determines the membership function of input language variable, 7 fuzzy subsets is taken in the quantized field of input language variable, wherein, it is above-mentioned
7 fuzzy subsets can between minus zone, zero section and positive section represent, in the present embodiment, different differences is provided and is corresponded to not
Same section, it is ensured that the parameter of corresponding PID regulator 10 can be calculated after different outlet air temperatures is obtained.
If for example, the newest actual exhaust air temperature value got is more than target exhaust temperature value in preset time, really
Determine difference to be located in first interval, i.e., when difference is negative, which belongs between minus zone；If the newest acquisition in preset time
The actual exhaust air temperature value arrived is equal to target exhaust temperature value, it is determined that and difference is located in second interval, i.e., when difference is zero,
The difference belongs to zero section；If the newest actual exhaust air temperature value got is less than target exhaust temperature value in preset time,
Then determine that difference is located in 3rd interval, i.e., when difference is positive number, which belongs to positive section.
Next, it is determined whether into PID output modes, that is, step S5 is performed, if it is judged that being no, is then continued to execute
Step S5.If it is determined that PID regulator 10 meets into after PID output modes, step S6 is performed, fuzzy quantity is converted into controlled quentity controlled variable
And export the aperture of controlled quentity controlled variable control electric expansion valve.Wherein, PID output modes include de-fuzzy step, de-fuzzy
Step includes：The fuzzy quantity of output is converted into precise volume by PID regulator 10, that is, obtains proportionality coefficient, the product of pid control algorithm
Divide coefficient and differential coefficient, and controlled quentity controlled variable is obtained according to proportionality coefficient, integral coefficient and differential coefficient, and export controlled quentity controlled variable
Control the aperture of electric expansion valve 30.As it can be seen that determining the parameter of PID regulator 10 by using fuzzy reasoning, can calculate current
Proportionality coefficient, integral coefficient and the differential coefficient of pid control algorithm, and controlled quentity controlled variable control electricity can be exported according to above three parameter
Sub- expansion valve opening greatly improves and adjusts efficiency and adjusting accuracy.
So adjusting method of the invention can calculate actual exhaust air temperature by timing sampling actual exhaust air temperature value
With the rate of the variation of the difference and actual exhaust air temperature of target exhaust temperature, fuzzy push away is carried out according to the difference and rate
Reason, can correct the parameter of pid control algorithm, and can calculate electronic expansion according to the parameter of above-mentioned pid control algorithm
Valve opening simultaneously drives electric expansion valve, so that using the frequency-conversion air-conditioning system fast and stable of electric expansion valve throttling, exhaust
Fluctuate it is small, and convertible frequency air-conditioner operation it is more energy saving, cooling and warming speed is faster.
