In one embodiment, the air outlet mode includes:
a blowing-off mode, a blowing-off and lower air-out mode, a separation lower air-out mode, a lower air-out mode and a front air-out mode.
In an embodiment, referring to fig. 2, the step S1 specifically includes the following steps:

and S212, acquiring the opening degree of a motor air door of the air outlet mode of the air conditioner according to the acquired air volume deviation of each time point of the air outlet of the air conditioner.

and carrying out numerical value conversion on the acquired air volume deviation of each time point of the air outlet of the air conditioner according to the following formula to acquire the opening degree of a motor air door under the air outlet mode of the air conditioner:

In the PID, P represents proportion (proportionality), I represents integral (integral), and D represents derivative (derivative).
In one embodiment, proportional (P) control is the simplest control, and is represented by the proportional relationship of the output of the controller to the input error signal. There is a Steady state error in the system output when there is only proportional control (Steady-state error).
In one embodiment, in integral (I) control, the output of the controller is proportional to the integral of the input error signal. For an automatic control System, if there is a Steady-state Error after entering a Steady state, the control System is called as having a Steady-state Error or simply a System with step-state Error. To eliminate steady state errors, an "integral term" needs to be introduced into the controller. The integral term integrates the error over time, increasing with time. Thus, even if the error is small, the integral term increases with time, which drives the output of the controller to increase to further reduce the steady state error to near zero. Therefore, the proportional Plus Integral (PI) controller can enable the system to have almost no steady-state error after the system enters the steady state.
In one embodiment, in derivative (D) control, the output of the controller is proportional to the derivative of the input error signal (i.e., the rate of change of the error). The automatic control system may oscillate or even destabilize during the adjustment to overcome the error. The reason for this is that the presence of a large inertia component (link) or a hysteresis (delay) component has the effect of suppressing the error, the variation of which always lags behind the variation of the error. The solution is to "lead" the change in the effect of the suppression error, i.e. when the error is close to zero, the effect of the suppression error should be zero. That is to say, it is not usually sufficient to introduce only a "proportional" term into the controller, which acts to amplify only the magnitude of the error, but to add a "derivative" term, which predicts the tendency of the error to change, so that a controller with proportional + derivative can bring the control action of suppressing the error to zero or even negative in advance, thus avoiding serious overshooting of the controlled quantity. Thus, for controlled objects with greater inertia or hysteresis, the proportional Plus Derivative (PD) controller can improve the dynamics of the system during adjustment.
In one embodiment, the magnitudes of the proportional, integral and derivative coefficients in the PID controller algorithm are determined based on the characteristics of the process being controlled. There are many methods for setting PID algorithm coefficients, and there are two broad categories in summary: the first is a theoretical calculation regularization method. The method is mainly based on a mathematical model of a system, and the parameters of the controller are determined through theoretical calculation. The calculated data obtained by the method can not be directly used, and must be adjusted and modified through engineering practice; the second engineering setting method is mainly dependent on engineering experience, is directly carried out in a test of a control system, is simple and easy to master, and is widely adopted in engineering practice. The engineering setting method of PID controller parameters mainly comprises a critical proportion method, a reaction curve method and an attenuation method. The two methods have the characteristics that the common point is that the controller parameters are adjusted according to an engineering empirical formula after passing a test. However, the controller parameters of the PID algorithm, i.e., the coefficients of the PID algorithm, obtained by any method need to be finally adjusted and refined in actual operation. The critical ratio method is generally used. The method for setting the PID controller parameters comprises the following steps: (1) firstly, a short enough sampling period is preselected to enable the system to work; (2) only adding a proportion control link until critical oscillation occurs to the input step response of the system, and recording a proportion amplification factor and a critical oscillation period at the moment; (3) and calculating parameters of the PID controller through a formula under a certain control degree.
In an embodiment, e (i) is defined as a difference between an actual air volume and a target air volume at the ith time point of the air outlet.
As described above, the time point division basis is a time point at which data is acquired at intervals of a preset acquisition cycle.
In an embodiment, after the step S1, the method further includes the following steps:
and step S22, when the target air volume of each air outlet of the air conditioner is achieved, controlling and outputting the opening degree of a motor air door of the corresponding air outlet for providing the opening degree as a basis of air conditioner comfort adjusting parameters for users.
