中文摘要:
针对高超声速目标拦截的制导问题,提出了一种带攻击角约束的协同制导律.在垂直弹目视线方向,由攻击角约束得到期望的终端视线角,利用非线性干扰观测器对模型中的干扰进行估计,结合非奇异终端滑模理论设计视线法向加速度指令,保证了每枚导弹与目标之间的视线角速率收敛到0且视线角收敛到期望的终端视线角;在沿弹目视线方向,基于二阶多智能体一致性算法设计视线方向加速度指令,保证了每枚导弹与目标之间的相对距离在有限时间内到达一致,进而保证各枚导弹同时击中目标.通过对4枚导弹协同拦截高超声速目标的情景进行仿真,验证了所设计制导律的有效性.
English Summary:
A cooperative guidance law was proposed for intercepting hypersonic target with constrained impact angle. In the direction of perpendicular to the line-of-sight (LOS), the acceleration command was developed based on the nonlinear disturbance observer and the nonsingular terminal sliding mode theory to ensure the LOS rate converging to zero and the LOS angle converging to the desired angle, i.e. the constrained impact angle. Along the LOS direction, the acceleration command was designed based on the multi-agent consensus control algorithm to ensure all the relative distances from the missiles to the target reaching the agreement in finite time and every missile hitting the target at same time. Simulation results for the scenario of four missiles intercepting a hypersonic target demonstrate the effectiveness of the proposed guidance law.
