末制导弹药捷联制导控制一体化技术研究

Research on strapdown integrated guidance and control technology of terminal guided munitions

建立了制导控制一体化系统的数学模型,设计非线性扩张状态观测器对系统不确定性进行了在线估计;基于动态面滑模理论,对制导控制系统进行了一体化设计,使弹体以特定角度命中目标,同时满足捷联导引头的视场角约束;为提高系统的抗干扰能力,在控制律中对观测器估计的系统不确定性进行了动态反馈补偿;利用李雅普诺夫理论证明了算法的稳定性;最后,通过六自由度弹道仿真验证了所提算法的正确性与有效性。

Based on the above reasons,the integrated guidance and control design technology of its should be studied.The mathematical model of the integrated system was established,and the nonlinear extended state observer was designed to realize the online estimation of the system uncertainty.Based on the dynamic surface sliding mode theory,the integrated design of guidance and control system was applied to make the missile attack the target at a specific angle and satisfy the constraint of the strapdown seeker field of view;In order to improve the anti-jamming capability,dynamic feedback compensation was carried out for the system uncertainty estimated by the observer in the control law;The stability of the algorithm was analyzed using Lyapunov theory;The six degree of freedom trajectory simulation proved the correctness and effectiveness of the proposed algorithm.
