Description
Technical Field
The invention relates to the field of self-adaptive control, in particular to an anti-choking wind power regulation and control platform.
Background
The self-adaptive control is the same as the conventional feedback control and the optimal control, and is a control method based on a mathematical model, and the difference is that the prior knowledge about the model and the disturbance, which is the basis of the self-adaptive control, is less, and the information about the model needs to be continuously extracted in the running process of the system, so that the model is gradually improved.
Specifically, model parameters can be continuously identified based on input and output data of the object, and this process is called online identification of the system. With the continuous production process, the model can become more accurate and closer to reality through online identification. Since models are constantly being developed, it is clear that the control actions integrated on the basis of such models will also be constantly being developed. In this sense, the control system has a certain adaptability. For example, when the system is in the design stage, the system may not perform well when being put into operation at the beginning due to the lack of initial information of the object characteristics, but as long as a period of operation elapses, the control system gradually adapts to adjust itself to a satisfactory working state through online identification and control. For example, certain control objects may have characteristics that vary significantly during operation, but the system can also adapt gradually by identifying and changing the controller parameters online.

the wind power control equipment is arranged above the barbecue table, is connected with the density identification equipment and is used for determining corresponding wind power intensity based on the received smoke distribution density so as to execute the blowing-off action of smoke above the barbecue table;
in the wind power control device, determining the corresponding wind power intensity based on the received smoke distribution density to perform the blowing action of the smoke above the barbecue table comprises: the higher the received smoke distribution density is, the higher the corresponding wind power intensity is;

Detailed Description

Smoke (smog) is a composite word of soot (smoke) and fog (fog) created in 1905 by the english human woi chi (h.a.voeux).
The smoke is originally a mixture of bituminous coal in the air and natural fog. The term is used to broadly refer to a mist (such as London smoke) generated by the condensation of industrial solid dust, or a mist formed by the photochemical reaction of a hydrocarbon and a nitrogen oxide (such as photochemical smoke of los Angeles) with a mixture of multiple pollutants.
Smoke in chemistry is generally referred to as dust and mist is generally referred to as liquid. Chemically, the combustion products of phosphorus in chlorine gas are 2: PCl3 and PCl5, in liquid and solid form respectively, so that a white smoke is visible.
