Embodiment
For making technical solution of the present invention clearer, below in conjunction with drawings and the specific embodiments, the present invention is described in further details.
Referring to Fig. 1, the specific embodiment as PG motor control method provided by the invention, comprises the steps:
Step S100, detection is in real time equipped with the air ducting state of the air conditioner of PG motor;
Step S200, according to air ducting state, calls corresponding pid algorithm parameter, controls the operation of PG motor.
PG motor control method provided by the invention, is equipped with the air ducting state of the air conditioner of PG motor by real-time detection, and according to the air ducting state detecting, and calls accordingly for controlling the pid algorithm parameter of PG motor speed, controls the operation of PG motor.It is equipped with the air ducting state of the air conditioner of PG motor by combination, select different pid algorithm parameters to control the operation of PG motor, improved the precision of PG Electric Machine Control, reduced the fluctuation of speed causing due to load variations in PG motor operation course, promoted the stability of PG Electric Machine Control, thereby it is larger to have solved PG motor speed deviation, the problem of fluctuation of service.
Wherein, it should be noted that, air ducting state comprises: sweep that wind is opened and with fixed angle wind-guiding.Because wind is swept in air ducting unlatching, and the wind-guiding angle that air ducting is not opened while sweeping wind with fixed angle wind-guiding is different, and the fans load that is equipped with the air conditioner of PG motor changes different.According to air ducting, whether open and sweep wind, and the wind-guiding angle of air ducting during with fixed angle wind-guiding, adjust pid algorithm parameter, and then control PG motor and move, can effectively reduce because fans load changes the different fluctuations of speed that cause PG motor, improve the control precision of PG motor, guarantee the stability of PG motor operation, thereby guarantee the stability of air conditioner air-out, improve user's comfortableness.
Preferably, as another specific embodiment of PG motor control method provided by the invention, execution step S100, before detecting in real time the air ducting state of the air conditioner that is equipped with PG motor, also comprises the steps:
Step S010, according to air ducting state, divides the control interval of PG motor;
Step S020, according to control interval, adjusts proportionality coefficient, integral coefficient and differential coefficient in pid algorithm, and stores.
Referring to Fig. 2, it should be noted that step S010, according to air ducting state, divides the control interval of PG motor and can realize as follows:
Step S011, the rotating speed deviation of test PG motor under air ducting state;
Step S012, according to rotating speed deviation, divides the control interval of PG motor.
Test by experiment, record is equipped with the air ducting dynamic sweeping wind of the air conditioner of PG motor, and the rotating speed deviation of PG motor while resting on each position with fixed angle wind-guiding, the rotating speed deviation under different air ducting states according to PG motor then, divides the control interval of PG motor.As: when air ducting is swept wind unlatching, the control interval of PG motor is that dynamic sweeping wind is interval; When air ducting is swept wind and do not opened with fixed angle wind-guiding, the control interval of PG motor is that fixed angle is interval.
Test by experiment and record the rotating speed deviation of PG motor under different air ducting states, and divide on this basis the control interval of PG motor, make the control interval of the PG motor divided more meet the running environment of current PG motor.And, while adjusting pid algorithm parameter according to divided control interval, can be by the air ducting combinations of states of air conditioner to in pid algorithm parameter adjustment process, reached the operation of PD motor can be with the variation of actual conditions real-time change.
Meanwhile, also guaranteed, according to air ducting state, to call the accuracy of corresponding pid algorithm parameter, made the operation of the PG motor current actual environment of more fitting, thereby promoted the comfortableness of air conditioner.
When according to air ducting state, divide after the control interval of PG motor, need to, according to control interval, adjust proportionality coefficient, integral coefficient and differential coefficient in pid algorithm parameter.
Concrete, when air ducting state is opened for sweeping wind, now the control interval of PG motor is that dynamic sweeping wind is interval, the differential coefficient in capable of regulating pid algorithm parameter is the first differential coefficient.
When air ducting state is during with fixed angle wind-guiding, the control interval of PG motor is that fixed angle is interval, and the differential coefficient in pid algorithm parameter can be adjusted to the second differential coefficient.
It should be noted that, the first differential coefficient is greater than the second differential coefficient.
This is due to when air ducting state is opened for sweeping wind, the control interval of corresponding PG motor is that dynamic sweeping wind is interval, now, the big or small real-time change of the air outlet of the air conditioner of outfit PG motor, the fans load of air conditioner changes greatly, therefore need to increase the differential coefficient in pid algorithm parameter.As a kind of embodiment, the pid algorithm parameter after adjustment can be: proportionality coefficient=8, integral coefficient=0.1, differential coefficient=5.
When air ducting state is during with fixed angle wind-guiding, the control interval of corresponding PG motor is that fixed angle is interval.Now, the size of the air outlet of the air conditioner of outfit PG motor is fixed, and therefore, when the fans load of air conditioner changes with respect to dynamic sweeping wind, the fans load of air conditioner changes relatively little.Now the differential coefficient in pid algorithm parameter can suitably reduce (the first differential coefficient while being dynamic sweeping wind with respect to air ducting state in corresponding pid algorithm parameter).Therefore, the differential coefficient of adjusting in pid algorithm parameter is the second differential coefficient, and makes the second differential coefficient be less than the first differential coefficient.
Concrete, when air ducting state is during with fixed angle wind-guiding, as a kind of embodiment, fixed angle interval (being the control interval of corresponding PG motor) can be take a plurality of fixed angles subinterval of predetermined angle after interval is divided the wind-guiding angle of air ducting.And the second differential coefficient in pid algorithm parameter corresponding to the plurality of fixed angle subinterval reduces with the increase of wind-guiding angle.
Wherein, the span of predetermined angle can be 30 degree-90 degree.
As take predetermined angle as 30 degree be example:
When predetermined angle is 30 while spending, due to the wind-guiding angle of air ducting be 0 degree to 180 degree (being that wind-guiding angle is more than or equal to 0 degree and is less than or equal to 180 degree), 30 degree of therefore take are divided to wind-guiding angle the fixed angle subinterval obtaining as interval and are respectively: (0 spends, 30 degree], (30 degree, 60 degree], (60 degree, 90 degree], (90 degree, 120 degree], (120 degree, 150 degree], and (150 degree, 180 degree].
Thus, the control interval (be fixed angle interval) that obtains PG motor comprise (0 degree, 30 degree], (30 degree, 60 degree], (60 degree, 90 degree], (90 degree, 120 degree], (120 degree, 150 degree], and (150 degree, 180 degree].Due to different control intervals, varying in size of the air outlet of the air conditioner of outfit PG motor, causes the fans load of air conditioner to change different.Therefore, need to adopt different pid algorithm parameters to control the operation of PG motor, to reach the object of the precision and stability that improves PG Electric Machine Control.
As: when the control interval of PG motor by (0 degree, 30 degree] forward to (30 degree, 60 degree] time, when the wind-guiding angle of air ducting becomes large, now, the air outlet that is equipped with the air conditioner of PG motor becomes large, causes the fans load of air conditioner to diminish.Therefore, can reduce the differential coefficient in pid algorithm parameter.As a kind of embodiment, the differential coefficient in capable of regulating pid algorithm parameter, makes differential coefficient reduce with the increase of the wind-guiding angle of air ducting.
More specifically, take predetermined angle as 90 degree, 90 degree of take are divided to wind-guiding angle a plurality of fixed angles subinterval obtaining as interval and are done further and describe in detail as example.
When predetermined angle is 90 while spending, the fixed angle subinterval now obtaining be respectively (0 degree, 90 degree] and (90 degree, 180 degree], the control interval of PG motor comprise (0 degree, 90 degree] and (90 spend, and 180 spend].
When the control interval of PG motor is (0 degree, 90 degree] time, while being air ducting open angle less (wind-guiding angle is less than 90 °), the air outlet of air conditioner is less, air-out is relatively unstable, the blower fan of air conditioner load variations in rotary course is larger, therefore, differential coefficient in pid algorithm parameter needs to increase, but increase amplitude should be less than air ducting and open the amplitude while sweeping wind, therefore capable of regulating pid algorithm parameter is particularly: proportionality coefficient=10, integral coefficient=0.2, differential coefficient=4.
When the control interval of PG motor is (90 degree, 180 degree] time, while being the open angle large (wind-guiding angle is greater than 90 °) of air ducting, the air outlet of air conditioner is larger, and air-out is relatively stable, the fans load of air conditioner changes less, therefore, the differential coefficient in pid algorithm parameter is corresponding less, therefore adjusts pid algorithm parameter to be: proportionality coefficient=10, integral coefficient=0.2, differential coefficient=3.
When adjusting the pid algorithm parameter (proportionality coefficient in pid algorithm of PG motor at different control intervals, integral coefficient and differential coefficient) after, the pid algorithm parameter that the different control intervals of adjusting are corresponding is preserved, when PG motor moves, by real-time detection, be equipped with the air ducting state of the air conditioner of PG motor, determine the control interval of PG motor, and then call corresponding pid algorithm parameter, improved the stability of PG motor operation.
At this, it should be noted that, pid algorithm parameter can determine according to many experiments result, guaranteed the accuracy of the pid algorithm parameter obtained.
Accordingly, based on same inventive concept, for realizing above-mentioned any PG motor control method, the present invention also provides a kind of PG electric machine control system, because operation principle and the PG motor control method principle provided by the invention of PG electric machine control system provided by the invention are same or similar, therefore repeat part, repeat no more.
