Abstract

The invention discloses a method for guiding an input constraining differential game based on self-adaptive dynamic planning. According to the method, a solving problem of an HJI equation and an input saturation problem in a nonlinear differential game problem are solved; an input constraining solving problem of the nonlinear differential game is solved by virtue of a self-adaptive dynamic planning technique, and a neural network and a Lyapunov method are combined so as to obtain a guidance control volume; and an input constraining differential game guidance law can be online obtained in real time based on an evaluation network updating law, and the aspect angle velocity in a guided missile-target relative motion relation tends to 0, so that the successful interception is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aircraft guidance, in particular to an input-limited differential countermeasure guidance method based on adaptive dynamic programming. Background technique [0002] The increasing diversification of modern and future combat environments makes the design of missile guidance law more and more prominent its irreplaceable role. With the rapid development of aerospace technology, various highly maneuverable, intelligent, and dexterous targets (such as tactical ballistic missiles, intelligent drones, and intelligent cruise missiles, etc.) are emerging. This brings serious challenges to the guidance and control technology of the interceptor. The traditional guidance law (proportional guidance) has been widely used in actual combat systems because of its simple structure and easy implementation. However, in the face of various new types of mobile intelligent targets, the guidance accuracy of traditional guidan...
