| 摘 要： | 应用PWPF(Pulse Width Pulse Frequency)调制技术研究空间动能拦截器的末制导律设计问题。针对PWPF调节器参数设置上的局限性,提出了一种非线性优化目标函数,综合考虑了PWPF调节器的线性工作区要求及脱靶量、燃料消耗量等制导系统的性能指标要求。利用提出的优化目标函数,应用遗传算法对PWPF调节器参数进行优化设计,并进行了仿真研究。仿真结果表明了该方法的有效性。

| Abstract: | PWPF(Pulse Width Pulse Frequency) modulation technique is applied to the terminal guidance law design problem of space kinetic killing vehicle (KKV) interceptor. To facilitate the selection of PWPF modulator parameters, a nonlinear optimizing objective function is proposed, which is associated with both the PWPF linear zone requirement and guidance performance parameters requirements, such as miss distance and fuel consumption. By the proposed optimizing objective function, genetic algorithm is applied to optimize the PWPF parameters, and simulation research is conducted. The simulation results validate the effectiveness of the approach. |
