Embodiment Construction
[0042] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0043] The present invention is a new variant loitering bomb flight system control method. First, the modeling process of the variant loitering bomb is studied, and the main aerodynamic parameters of the variant loitering bomb are analyzed at different speeds and sweep angles. Change law, obtained the linear state space model of variant loitering bomb including deformation parameters; research variant loiter bomb based on L 1 The flight control law design of adaptive control, the design of state predictor and low-pass filter for external disturbance and high-frequency oscillation of system control input can effectively improve the control effect of the variant loitering missile.
[0044] The present invention comprises the following steps:
[0045]Step 1: Accurate modeling of variant loitering missiles. The specific functional relationship between the main aero...
