| 摘 要： | 通过分析激光末制导炮弹比例导引制导律几何关系和原理,研究了激光末制导炮弹的工作原理,建立了含非线性进动的激光陀螺式导引头动力学模型和线性化弹体模型的末制导炮弹比例导引回路模型.根据制导控制系统是否利用导引头非线性进动信号作为制导信号,建立了两种制导控制系统数学模型,采用不同的制导时间以及弹体参数,进行了末制导炮弹比例导引回路仿真,对比分析了两种制导控制系统的性能.最后,针对非线性系统易引起弹体姿态较大摆动的问题,提出了在制导时间有限时的基于衰减系数的激光末制导炮弹改进制导方案.

| Abstract: | By analyzing the proportional navigation guidance plane geometry and principle of the terminal laser-guided projectile,the working principle of terminal laser-guided projectile were studied.Then the loop model of terminal laser-guided projectile proportional navigation law including a nonlinear-procession laser-gyro stabilized dynamic seeker and a linear airframe was established.Especially,focusing on whether guidance and control system used the seeker' s nonlinear procession signal as the guidance command,... |
