| 摘 要： | 基于红外/毫米波复合导引系统,针对空地导弹攻击地面目标问题,提出了一种新的具有强鲁棒性的非线性末制导律.基于弹目相对运动学的非线性关系,以相对距离作为状态,同时将目标机动作为系统有界扰动,建立了弹目相对运动的数学模型.基于红外和毫米波复合导引系统获得的测量信息,采用滑动模态控制方法,以优化制导精度为目标,设计了一种自适应非线性变结构控制律.该方法利用Lyapunov稳定理论严格证明了制导闭环系统的全局渐近稳定性.数字仿真表明,这种制导律对地面运动目标具有很强的鲁棒性和适应性,并能获得良好的制导精度. |

| Abstract: | For the case of air-to-surface missile with guidance system composed of infrared system and millimeter wave system against ground targets,a new design scheme of nonlinear terminal guidance law with robustness is proposed.An engagement model in the pitch plane is formulated,in which states are chosen as relative distance and relative velocity,by combining the relative relationship between missile and target,where the information is obtained directly from the infrared system and millimeter wave system.By adop... |
