摘要
小灵巧炸弹是一种采用倾斜转弯(BTT)控制方式的小型面对称电视制导航空弹药,在实际飞行中必须确保其导引头框架角不超出可用范围。针对上述问题,根据时变偏置比例导引的思想,在三维空间中设计视线角速率偏置项,通过姿态角时变修正实现框架角约束,提出了一种带导引头框架角约束的三维纯比例导引律。仿真结果表明该方法在保证小灵巧炸弹战技指标要求的同时有效减少了框架角需求。
The Small Smart Bomb is a kind of symmetrical TV-Guidanee bomb unit which adopts Bank- To-Turn （BTT） control method, and the frame angel restriction of TV-seeker must be satisfied during practical flight. Aiming at this problem, by using the thought of TV-BPN and redesigning the biased item of line-of-sight rate in 3D space, a 3D Pure Proportional Guidance Law with frame angel restriction which realized frame angel constraints through gesture angel correction is proposed. Simulation results show that the frame angels of TV-seeker and the time need to hit target are both reduced.
