Between timesharing, initial value is I, is connected with display by pic chip, the temperature data that display real-time displays temperature sample circuit gathers,
And temperature data is shown in real time by temperature curve.
First, carrying out the debugging of scale parameter P, set pid parameter initial value as I as infinitely great, I is set to by specific experiment
9999, d=0, P=1, make PID become a pure proportional algorithm, now change P numerical value, observe temperature sampling electricity by display
The temperature data that road gathers, until temperature curve is damped oscillation, transit time is shorter, obtains suitable proportional band, really
Certainty ratio FACTOR P is 7.
The time of integration I: integral action eliminate atomization control device steady-state error.In the case of proportionality coefficient P is certain,
The time of integration, I was the least, and integral action is the strongest, and I is too small there is a possibility that atomization controls device instability, therefore, sets initial integration
Time is 100s, and by great many of experiments, atomization controls device to be occurred substantially postponing, and therefore, I should select suitably to be worth, the most really
Definite integral time I is 50s.
Through great many of experiments, native system does not use differential to regulate.

Shi Bianhua, as it is shown on figure 3, Fig. 3 figure below represents electrothermal tube temperature curve ideally, upper figure is the atomization that the present invention provides
Controlling the temperature curve that device obtains, in actual application, staff sets fiducial temperature according to plant capacity grade, and PIC is mono-
Sheet machine obtains feedback temperature by electrothermal tube, and by poor to described feedback temperature and fiducial temperature, obtains feedback temperature and benchmark
The difference of temperature, described difference is temperature allowance, and PIC single chip microcomputer carries out the real-time regulation of PWM duty cycle by temperature allowance.
Being found out by figure, the temperature curve that the present invention provides is damped oscillation, and later stage hunting range is less.When fiducial temperature and feedback temperature
When degree difference is the least, the output of PWM pulse duty cycle that atomization controls device is almost nil, because there is no need to carry out high-power
Heating, when fiducial temperature and feedback temperature differ greatly, in order to realize oepration at full load to reach fiducial temperature, atomization controls
The output duty cycle of device is close to 1, i.e. atomization controls the temperature curve of device close to temperature curve ideally.
The present invention uses PWM pulse modulation technology, reduce tradition atomization control process present in temperature fluctuation big
Problem, makes the temperature of aerosol be maintained in certain interval range, and the spray amount then making the electrothermal tube mouth of pipe is stable, actual
In application, comfort level is higher, simultaneously as temperature fluctuation range is little so that atomization more fully and is stablized.
Although the detailed description of the invention of the present invention is described by the above-mentioned accompanying drawing that combines, but not the present invention is protected model
The restriction enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme, and those skilled in the art are not
Need to pay various amendments or deformation that creative work can make still within protection scope of the present invention.
