中文摘要
      在大口径舰炮网络化制导弹药打击近岸机动目标的末制导段, 提出了一种含攻角约束的有限时间分布式模糊协同制导律. 构建含攻角约束的网络化弹药-目标二维相对运动模型, 设计双扩张状态观测器估计目标在速度切向、法向上的加速度. 为保证命中时刻在有限时间内趋于一致, 在视线方向基于分布式协同控制与有限时间稳定理论, 采用积分滑模设计分布式有限时间协同制导律; 在视线法向, 为在有限时间内零化视线角误差、视线角速率并改善控制指令终点发散现象, 采用非奇异终端滑模设计了含攻角约束的两阶段制导律; 设计模糊自适应逼近器削弱控制指令抖振, 并补偿干扰. 通过Lyapunov第二法证明了全系统状态的一致最终有界性与有限时间收敛性. 仿真实验表明: 该制导律使网络化弹药在打击机动形式不同的目标时, 均具备较好的协同制导性能.
英文摘要
      In the terminal guidance section of large caliber naval gun networked guided projectiles while striking near shore maneuver target, a finite time distributed fuzzy cooperative guidance law was proposed with impact angle constraint. The two-dimensional relative motion model of networked projectiles and target with impact angle constraint was constructed, and double extended state observer(ESO) was designed to estimate target acceleration at tangent and normal of velocity. Aiming at guaranteeing the consensus of impact times in finite time, integral sliding mode was adopted to designed distributed finite time cooperative guidance law in the line-of-sight(LOS), based on the distributed cooperative control and finite time stability theory. In vertical LOS, in order to zeroing the error and angular of LOS angle in finite time, as well as improving terminal divergence phenomenon of control instruction, a guidance law with impact angle was designed by nonsingular terminal sliding mode. Fuzzy adaptive approximator was applied to weaken the chattering of control instruction and compensate interference. The states of whole system are all uniformly bounded and finite time convergence, which is proved by Lyapunov second method. Simulation experiment shows this guidance law makes networked projectiles posses well guidance performance while striking targets with different acceleration forms.
