Detailed Description
Some embodiments of the invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of main steps of a temperature control method according to an embodiment of the present invention, which may include:
step S11: heating to a temperature rise under full load power in response to a control instruction for heating to a set temperature;
step S12: judging whether the absolute value of the difference between the current temperature and the set temperature is smaller than or equal to a first preset threshold value;
if yes, go to step S13;
step S13: and regulating and controlling the current temperature based on a proportional-integral-derivative algorithm so as to enable the current temperature to reach the set temperature.
In some embodiments, the temperature control method provided by the embodiment of the invention can be applied to electronic equipment provided with heating equipment, such as an oven, and the like, and the target temperature control effect can be achieved quickly and efficiently by adopting the temperature control method provided by the embodiment of the invention.
In the following, an electronic device will be described as an example of an oven provided with a heating device, such as a heating tube, which may be provided with at least one heating tube, and in some embodiments, step S11 may be specifically performed in response to a control command to heat to a set temperature, controlling the heating tube combination activated in the current heating mode to perform heating-up heating at full power. The heating-up and heating are carried out under full-load power without introducing PID algorithm control, so that the heating-up speed in the heating-up stage can be improved, and the control efficiency is improved.
Wherein the set temperature may be determined based on a user's setting. The heating tube combination may be preset, and as an example, the current heating mode may be a mode of starting back tube windup of the oven.
In the embodiment of the invention, the current temperature is changed along with different temperature control stages or time of the temperature control flow, and the current temperature can be the actual temperature acquired in real time.
In some embodiments, the first preset threshold may be set according to requirements, and as an example, the first preset threshold may be set to 1 ℃.
In the embodiment of the present invention, by executing step S12, whether to enter the regulation stage can be determined according to the determination result. And when the judgment result is yes, determining that the regulation stage can be entered, and executing the step S13. The temperature control stage can be automatically identified, so that different temperature control strategies can be adopted for different temperature control stages.
In some embodiments, step S13 may specifically be to preset values of the proportional parameter Kp, the integral parameter Ki, and the derivative parameter Kd in the PID algorithm for the regulation stage, and perform temperature control based on the PID algorithm with the set parameters.
Because the temperature rising stage is not controlled by adopting the PID algorithm, the initial accumulated deviation is 0 when the temperature enters the regulation stage, if the temperature is directly regulated based on the initial accumulated deviation, the fluctuation is larger and the rapid realization of temperature stabilization is not facilitated, therefore, the initial accumulated deviation value can be determined first, the temperature is controlled by adopting the PID algorithm based on the initial accumulated deviation value, and referring to fig. 2, fig. 2 is a schematic flow chart of a specific implementation method of the step S13 provided by the embodiment of the invention, and the step S13 can be specifically:
step S131: determining an initial duty cycle of the heating device based on the set temperature;
step S132: determining an accumulated deviation initial value in a proportional-integral-derivative algorithm according to the ratio of the initial duty ratio of the heating equipment to a preset integral parameter;
step S133: based on the accumulated deviation initial value and the initial duty ratio of the heating equipment, the current temperature is regulated and controlled by adopting a proportional-integral-derivative algorithm.
In some embodiments, step S131 may be specifically:
acquiring an association relation between a historical set temperature and a stable duty ratio;
and determining the initial duty ratio based on the set temperature and the association relation.
The stable duty cycle may be a duty cycle corresponding to a time when the actual temperature is stabilized at the history setting temperature, in which temperature control is performed in response to an instruction to heat up to the history setting temperature.
As an example, the association relationship of the history setting temperature and the steady duty ratio may be expressed as: η (eta) Stabilization ＝a 1 *T s +b 1 Wherein eta Stabilization Represents a steady duty cycle, T s Representing the historical set temperature, a 1 B is a coefficient of association 1 Is constant.
Substituting the set temperature into the above relation can reach a stable duty ratio corresponding to the current set temperature, and the stable duty ratio is used as the initial duty ratio of the heating equipment after entering the regulation and control stage.
In the embodiment of the invention, the output controlled by the PID algorithm is equal to the sum of the products of the proportional term, the integral term and the differential term, wherein the proportional term is equal to the product of the proportional parameter and the deviation, the integral term is equal to the product of the integral parameter and the accumulated deviation, and the differential term is equal to the product of the differential parameter and the deviation change rate. In the beginning of the regulation phase, the proportional term and the differential term are transient terms, so that the preliminary estimation is not needed, and the value can be assigned to 0. Correspondingly, the initial duty ratio of the heating device is used as the output of the PID algorithm control, and in step S132, the initial value of the cumulative deviation may be determined according to the ratio of the initial duty ratio of the heating device to the preset integral parameter.
In some embodiments, step S133 may be specifically:
in the regulation stage, the initial duty ratio of the heating equipment is used as an initial duty ratio to control the heating pipe to heat in a combined mode, and an accumulated deviation initial value is set as an initial value of initial adjustment of integral parameters of a PID algorithm;
acquiring the current temperature and calculating the deviation between the current temperature and the set temperature;
the PID algorithm calculates the required duty ratio according to the values and the deviation of a proportional parameter Kp, an integral parameter Ki and a differential parameter Kd in the PID algorithm which are preset for the regulation and control stage;
the heating pipe combination is controlled to work based on the required duty ratio, so that the heating power of the heating pipe combination is controlled, and the current temperature reaches the set temperature.
When the PID algorithm is introduced to control the temperature at the beginning of the regulation stage, the initial duty ratio and the accumulated deviation initial value of the heating equipment are determined, so that the current temperature can reach the set temperature more quickly, and the overall efficiency of the temperature control can be further improved.
The above is a temperature control method provided by the embodiment of the invention, in which heating is performed under full power in a heating stage by responding to a control instruction for heating to a set temperature, whether to enter a regulation stage is determined by judging whether the absolute value of the difference between the current temperature and the set temperature is smaller than or equal to a first preset threshold, and if so, the current temperature is regulated based on a proportional-integral-derivative algorithm, so that the current temperature reaches the set temperature. On one hand, the method can automatically identify the temperature control stage, and different temperature control strategies can be adopted for different temperature control stages; on the other hand, PID algorithm control is not introduced in the heating stage, PID algorithm control is introduced in the regulation stage, full-load power is adopted in the heating stage to heat, the problem of low heating speed in the existing heating stage is solved, the efficiency of the whole temperature control process is improved, and the target temperature control effect can be achieved quickly.
In some embodiments, for precise control and energy saving, the full-open stop temperature of the heating stage can also be determined, and heating in the heating stage can be stopped in time, which is described in detail below.

In some embodiments, step S33 may specifically be stopping the heating up at the full load power when the current temperature is greater than or equal to the full-open stop temperature.
As an example, the set temperature is 200 ℃, the full-open stop temperature is 185 ℃, and when the heating is performed to 185 ℃ with full power, the heating is controlled to stop, and the temperature still rises within a certain time after the heating is stopped. By stopping heating when the full-open stop temperature is reached, the situation that the currently measured temperature 185 ℃ caused by the lag of the temperature sensor or other reasons is smaller than the actual temperature and the actual temperature is close to or equal to the set temperature can be avoided, and the effects of accurately controlling the temperature and saving resources can be further achieved on the basis of achieving the same beneficial effects as those of the corresponding embodiment of the above-mentioned figure 1.

step S42: and determining the full-open stop temperature corresponding to the current set temperature according to the fitting model and the relation between the set temperature and the historical heating stop temperature and the historical overshoot temperature.
In some embodiments, step S41 may specifically be to perform linear fitting according to a plurality of historical heating stop temperatures and historical overshoot temperatures corresponding to the respective historical heating stop temperatures, so as to obtain a fitting model. As an example, a linear fit may be performed using a least squares method, and the resulting fit model may be expressed as:
T o ＝a 2 *T stop of +b 2 Wherein T is o Represents the historical overshoot temperature, T Stop of Representing the historical heating stop temperature, a 2 Coefficients representing the fitting model, b 2 Is constant.
In some embodiments, step S42 may be specifically:
the relationship between the set temperature and the historical heating stop temperature and the historical overshoot temperature can be expressed as: t (T) s ’＝T Stop of +T o Obtaining the current set temperature T according to the relation and the fitting model s ' the corresponding full-open stop temperature is equal to the set temperature T s ' sum constant b 2 The difference of (a) and the coefficient a of the fitting model 2 And a ratio of the sum of 1, i.e

if so, it is determined to enter the stabilization phase.
In some embodiments, step S57 may also be performed:
when the temperature control device enters a stable stage, a proportional-integral-derivative parameter combination which is different from a regulating stage for regulating the current temperature based on a proportional-integral-derivative algorithm is adopted for temperature control, wherein the value of at least one parameter in the proportional-integral-derivative parameter combination is smaller than the value of the corresponding parameter in the regulating stage.
The steps S51 to S55 may be implemented in the same manner as the steps S31 to S35, and for brevity, reference is made to the above description.
In the embodiment of the present invention, the preset duration and the second preset threshold in step S56 may be flexibly set according to the requirements.
The proportional-integral-derivative parameter combination can comprise proportional parameters, integral parameters, derivative parameters and values of the parameters of the PID algorithm.
In some embodiments, step S57 may specifically be to perform temperature control by using a PID parameter combination having a value of at least one parameter smaller than a value of a corresponding parameter in the regulation stage, and values of the remaining parameters may be the same as the values of the corresponding parameters in the regulation stage, so as to weaken regulation of the temperature by the PID algorithm in the stabilization stage, relative to the regulation stage for regulating the current temperature based on the PID algorithm when entering the stabilization stage.

In some embodiments, different control strategies may be used to control the temperature with respect to the magnitude of the fluctuation of the current temperature relative to the set temperature, so as to enhance the control of the PID algorithm during the steady phase when the fluctuation is relatively large, and to control the temperature during the steady phase when the fluctuation is relatively small. Step S57 may specifically be:

The third preset threshold value can be set according to requirements, and is larger than the second preset threshold value. As an example, the second preset threshold may be 1 ℃, and the third preset threshold may be 2 ℃.
Based on the above example, when the proportional parameter of the regulation stage is set to 1, the integral parameter is set to 1, and the differential parameter is set to 1, the proportional parameter in the first proportional-integral-differential parameter combination of the stable stage may be set to 0.5, the integral parameter may be set to 1, and the differential parameter may be set to 0, and the proportional parameter in the second proportional-integral-differential parameter combination may be set to 1, the integral parameter may be set to 1, and the differential parameter may be set to 0.
