Abstract

The invention relates to an aircraft real-time penetration trajectory generation method and system. According to the method, a second-order cone programming method is used to solve a penetration trajectory optimization problem, penetration trajectories under different initial conditions are obtained, after a data set is generated, a deep neural network is trained by using the generated data set, and a trained deep neural network model is obtained. And then the trained deep neural network model is used as a real-time controller of an attack angle and a heeling angle, and a penetration trajectory is rapidly generated based on the obtained current state parameters of the hypersonic gliding aircraft. In the actual application process, the penetration trajectory can be obtained only by inputting the obtained current state parameters, so that the solving efficiency of the convex optimization problem is improved, and the real-time requirement of the HGV highly dynamic environment is met.

Description

technical field [0001] The invention relates to the technical field of trajectory planning, in particular to a method and system for generating a real-time penetration trajectory of an aircraft. Background technique [0002] Hypersonic Gliding Vehicle (HGV) is a near-space vehicle with high-speed, large maneuvering and long-range gliding capabilities, and has broad application prospects. To counter missile defense systems, it is necessary to improve the penetration capabilities of HGVs. The effective penetration method of HGV is to take full advantage of its speed. Due to the development of cooperative guidance technology, HGV needs to penetrate multiple interceptors and reach the target area. And the engagement process is highly dynamic, and real-time decision-making performance is critical for HGVs. [0003] Ballistic optimization is an important field in the aerospace field. For HGV, ballistic optimization is an effective method to achieve penetration. However, there...
