战术导弹的鲁棒自校正制导及单片机实现

ROBUST SELF-TUNING GUIDANCE LAW FOR TACTICAL MISSILE AND ITS REALIZATION WITH SINGLE-CHIP MICROCOMPUTER

本文提出了战术导弹的一种新的制导方式——鲁棒自校正制导。这种制导方式将战术导弹高阶、非线性的复杂数学模型等效为低阶、线性时变模型,基于这种低阶等效模型设计了时变参数辨识及鲁棒自校正制导算法。仿真试验表明,战术导弹的鲁棒自校正制导有较高的命中精度和较强的抗干扰能力,特别是其工程实现容易。文中还讨论了制导系统单片机实现的一些问题。

This paper presents a new guidance law-robust self-tuning guidance law(RSTGL). In the RSTGL, the nigh order and nonlinear complex model of a tactical missile is equivalent to reduced-order and linear time-varying models. The identification algorithm for time-varying parameters and robust self-tuning guidance algorithm are proposed based on tnis equivalent reduced-order model. Simulation experiments have proved that the RSTGL has high hitting accuracy and aisturbance rejection ability. Especially, because of its simple structure, the RSTGL is easy to be implemented in engineering. Tnis paper also discusses some problems in the guidance system realization with single-chip microcomputer.
