Problems solved by technology

[0003] Nowadays, for the general differential game problem, it is usually difficult to obtain the exact analytical solution, in most cases, we can only find the numerical solution
Although experts and scholars from various countries have conducted a lot of research on solving differential game problems and proposed various algorithms, a general solution method for differential game problems has not yet been found.

Abstract

The invention relates to a solving method of an air posture Pareto attack and defense strategy and belongs to the solving of a multi-aircraft combined attack and defense strategy. The solving method includes: creating a continuously differentiable posture function; using the continuously differentiable posture function to build a Pareto differential game model; using a variational method principle to convert the Pareto differential game model into an optimal control model; using a Legendre pseudo-spectral method to convert the optimal control model into a nonlinear programming model; using an SNOPT solver to solve the nonlinear programming model to obtain the multi-aircraft combined attack and defense control strategy. The method has the advantages that multiple optimal combined attack strategies of a chasing party can be solved when an escaping party adopts an optimal escaping strategy; the solving results can be used as the reference standards for evaluating other attack and defense strategy solving technologies; the learning training of artificial intelligence solving technologies can be monitored.

Description

technical field [0001] The invention belongs to the technical field of solving multi-aircraft joint attack and defense control strategies, and in particular relates to a method for solving an air situation Pareto attack and defense strategy. Background technique [0002] With the development of scientific and technological means and changes in combat modes, compared with traditional combat methods, the modern battlefield environment is more complex, and the tactics and strategies of both sides on the battlefield are more changeable and unpredictable. This puts forward stricter requirements for the command and decision makers on the battlefield, who must be able to understand the situation changes on the battlefield in time to make real-time decisions. In complex multi-aircraft air combat environment, the traditional situation function provides powerful information for the change of air combat situation and the assessment of threat level. So far, neither the Nash differentia...
