对于战术导弹导引规律的研究,考虑到下列重要动态过程与随机效应:目标的随机运动,导引头的测量噪声,受限制的控制量,受限制的加速度以及导弹自动驾驶仪的动态过程。本文利用最佳随机控制理论,推导出几个不同的导引规律,并用计算机的模拟,来进行估价。本文的重要结论是,当导弹的机动能力显著地限制着拦击精度时,计及控制量饱和的控制方式,比控制量不受约束的控制方式,在性能上改善得多。
For the study of guided-missile tactics, the following important dynamic processes and stochastic effects are considered: stochastic motion of target, survey noise of seeker, restricted control volume, limited acceleration and dynamic process of missile autopilot. In this paper, we use the best stochastic control theory to derive several different guiding rules and use computer simulation to evaluate. The important conclusion of this paper is that when the maneuverability of a missile significantly limits the accuracy of the interception, the control mode that accounts for the saturation of the control volume is much better in performance than the uncontrolled control mode.
