| Sumario: | To solve the saturation attack problem of guided munitions, a three-dimensional impact time control guidance law with field of view constraint is proposed. The geometric model of guidance and interception is established in three-dimensional space. Based on three-dimensional proportional guidance law and considering the coupling of yaw and pitch channels, additional time error feedback control terms satisfying the spatial field of view constraint are designed by using the sliding mode control technology, so as to ensure that the guided munitions accurately hit the target with the expected attack time while satisfying the spatial field of view constraint. The stability of the proposed three-dimensional impact time control guidance law is strictly proved by Lyapunov stability theory. Finally, the effectiveness of the designed guidance law is verified by simulation comparison. |
