Abstract

The invention relates to a novel variant patrol bomb flight system control method. The method comprises steps of firstly, researching a modeling process of a variant patrol bomb, analyzing a change rule of main aerodynamic parameters of the variant patrol bomb under different speeds and sweepback angle motion states, and obtaining a linear state space model of the variant patrol bomb containing deformation parameters. The method is advantaged in that flight control law design of the variant patrol bomb based on L1 self-adaptive control is studied, and a state predictor and a low-pass filter are designed for external disturbance and system control input high-frequency oscillation so that the control effect of the variant patrol bomb is effectively improved.

Description

technical field [0001] The invention belongs to a novel adaptive control method of variant loitering missiles, which utilizes the improved L on the basis of the model reference adaptive control method 1 The adaptive control method suppresses the uncertain high-frequency oscillation in the deformation control process of the variant loitering bomb, and improves the stability and robustness in the deformation process of the variant loitering bomb. Background technique [0002] In order to cope with the complex battlefield environment in modern information warfare, military powers in the world have invested a lot of money and technicians to develop new concept weapons. Loitering bombs, as the product of the combination of drones and missiles, emerged as the times require, and have become the research and development of battlefield weapons in various countries. Focus and hot spots. As a rising star, loitering missiles have many advantages over drones, conventional missiles, crui...
