Aircraft parameter mapping system and method based on supporting vector machine and multiple regression

Abstract

Disclosed is an aircraft parameter mapping system and method based on supporting vector machine and multiple regression. The system comprises a data input module, a parameter mapping check module, a parameter mapping verification module, a parameter mapping confirmation module and a mapping display module. Through few aircraft-scheme-related response parameters and self-varying parameter data sample pairs, a parameter mapping relation between the response parameters and the self-varying parameter data sample pairs is established; data samples of part of the response parameters in the data sample pairs are allowed to contain errors or noise, a high-precision calculation model is replaced with parameter mapping to engage in optima design of aircraft overall schemes, the requirement for quickly acquiring optimal aircraft overall schemes is met, and optimizing efficiency is improved.

Description

technical field [0001] The invention relates to an aircraft parameter mapping system and method based on a support vector machine and multiple regression, and belongs to the field of aircraft overall scheme optimization design. Background technique [0002] With the application of optimization technology in the overall design of the aircraft, it satisfies the needs of quickly obtaining the optimized overall plan. In order to better solve the pre-screening process and select an optimal solution as soon as possible, it is impossible to use high-precision models for some specialties, and it is more hoped to obtain simple and accurate mathematical relationships through response parameters and independent parameters , and use it to replace the high-precision model. Parameter mapping analysis is an important auxiliary means to solve the rapid optimization design of the overall plan. Using the data sample pairs of response parameters and independent variable parameters generated b...

Problems solved by technology

At present, the method of establishing the parameter mapping relationship is usually to use the existing data samples to directly construct the mathematical relationship between the response parameters and the independent parameters, while ignoring the possible bad points in the data samples, that is, the parameter sample data contains errors or noise

[0003] The present invention proposes a parameter mapping analysis system and method based on support vector machine and multiple regression, which is used to establish the parameter mapping relationship between the response parameter and the independent variable parameter involved in the overall plan of the aircraft, and eliminate the error or noise caused by the data. According to the relevant literature retrieval at home and abroad, there is no relevant literature in the searched literature that is closely related to this technology
