But at the same time, it should also be pointed out that adaptive control is much more complicated than conventional feedback control, and the cost is also much higher, so only when conventional feedback cannot achieve the desired performance, it will be considered

Embodiment Construction

[0033] The implementation of the electronically assisted selection system and method using signal analysis of the present invention will be described in detail below.

[0034] The wind tunnel, also known as the wind tunnel laboratory, is an artificially generated and controlled airflow, which is used to simulate the flow of air around an aircraft or entity, and can measure the effect of the airflow on the entity and observe a pipe-like physical phenomenon. Experimental equipment, it is one of the most commonly used and most effective tools for aerodynamic experiments.

[0035] Wind tunnel experiments are an indispensable part of aircraft development. It not only plays an important role in the research and development of aviation and aerospace engineering, but also is indispensable in the fields of transportation, housing construction, and wind energy utilization with the development of industrial aerodynamics. With this experimental method, the flow conditions are easy to con...

Abstract

The invention relates to an electronic auxiliary selection system applying signal analysis, comprising: an array of air outlets, used as a power source for a wind tunnel, composed of multiple columns and rows of air outlets arranged side by side, and between every two adjacent air outlets The spacing is equal; the electronic control mechanism is connected to the air outlet array, and is used to control the number of air outlets in the air outlet array that is consistent with the number of on-site openings based on the received on-site opening quantity; The received real-time number of human bodies determines the corresponding on-site opening number. The invention also relates to an electronically assisted selection method using signal analysis. The electronic auxiliary selection system and method using signal analysis of the present invention are compact in design, safe and stable. Since the number of air outlets to be operated can be randomly selected based on the number of on-site personnel, and at the same time, the wind intensity can be weakened in time when the personnel's position is too high, thereby increasing the adaptive level of wind tunnel project management.

Description

technical field [0001] The invention relates to the field of self-adaptive control, in particular to an electronic auxiliary selection system and method using signal analysis. Background technique [0002] The research object of adaptive control is a system with a certain degree of uncertainty. The so-called "uncertainty" here means that the mathematical model describing the controlled object and its environment is not completely certain, which contains some unknown factors and random factors. [0003] Any actual system has different degrees of uncertainty, these uncertainties sometimes protrude inside the system, and sometimes protrude outside the system. From the inside of the system, the designer does not necessarily know the structure and parameters of the mathematical model describing the controlled object in advance. As the influence of the external environment on the system, it can be equivalently represented by many disturbances. These disturbances are usually unpr...
