Problems solved by technology

For the sequential design of OLHS, without deleting the existing sampling points and ensuring the basic structure of the LHS, there are two contradictions in the existing methods: the space filling of new samples and the flexibility of adding samples

Embodiment Construction

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] to combine figure 1, the present invention proposes a sequential experimental design method for missile strikes against moving targets, assuming that the initial sample size is n, the variable dimension is d, and the sample after the new sampling point is equivalent to a multiple of the initial sample is r, where n , d, r are all natural numbers; variable X j , the cumulative distribution function F of j=1,2,...,d j (·). Specific steps ar...

Abstract

The invention provides a sequential experimental design method for a guided missile to strike a moving target. The sequential experimental design method for the guided missile to strike the moving target comprises the following steps that an initial sampling point matrix is generated, an optimized sampling point matrix is generated, a corresponding sampling point matrix is calculated when Xn*d obeys U(0,1) distribution, a deviation matrix is calculated, a newly-increased sampling point matrix is calculated, an optimized sampling point matrix is generated, and whether sequential design is terminated or not is judged. According to the sequential experimental design method for the guided missile to strike the moving target, on the basis of not destroying an original OLHS sample structure andguaranteeing good space fallibility, new sampling points are increased by integral multiples of an original OLHS sample, and the sampling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of engineering optimization design, in particular to a sequential experiment design method for missiles to attack moving targets. Background technique [0002] In today's society, the rapid development of computer technology has effectively promoted the development of simulation technology. Due to the advantages of economy, safety, repeatability and non-destructiveness in the application of simulation technology, it is widely used in aerospace, electric power, chemical industry, nuclear energy, communication and other fields, and has achieved good application results. With the wide application of simulation technology, the simulation objects become more and more complex, and a single simulation takes a long time, that is, expensive simulation. For example, a single simulation of Ford Motor Company's bankruptcy model required 36 to 160 hours. When evaluating, analyzing, and optimizing the performance / effect...
