摘要
本文在给定七种不同初始条件、不同目标机动和选取快、慢两种时间常数,不同升力,不同导引比及制导逻辑设计的条件下,采用简化控制模型,研究了BTT-90导弹的比例导引规律,并对系统的性能进行了分析。结果表明,BTT-90导弹采用比例导引规律是完全可行的,设计的制导逻辑是正确的。模型简单,计算精度好,工程上容易接受。本文及其计算程序为BTT系统参数(导引比、控制器时间常数,弹体升力系数等)选择提供了依据。
In this paper, proportional guidance law is studied and system perpermance is analysed to BTT-90 missile, on the conditions of given seven kinds of different initial states, different target maneuvering, two kinds of time constants (fast, slow), different lift, different guidance ratios and guidance logical designs. Here a simplified control model is used. The results show complete feasibility of the adopted proportional guidance law and correctness of the guidance logical design for BTT--90 missile. The model is simple and the calculation is of satisfactory precision, so it is much acceptable in engincering. The results and computational programs in this paper can provide criteria for the Aelection of BTT missile system parameters (guidance ratio, controller time constant, lift coefficient of body, etc).
