静不稳定BTT导弹飞控系统的设计与分析

本文给出了倾斜转弯导弹简化的数学模型，研究了航向静不稳定弹体的气动特性，应用经典控制理论，提出了这类导弹飞控系统的设计方法和设计目标，并以某型ＢＴＴ－９０导弹为对象，给出了整个控制系统的设计过程，进行了非线性数字仿真，仿真结果表明，设计达到了ＢＴＴ导弹战术技术指标的要求。

THE DESIGN AND ANALYSIS OF FLIGHT CONTROL SYSTEM FOR A STEADY UNSTABLE BTT MISSILE

The simplified mathematical model for a bank-to-turn (BTT) missile is presented. Based on the research of aerodynamics of an yaw steady unstable missile,the design methodology and design goals for this kind of BTT missile flight control system are discussed using classiCal design techniques.The design procedure of flight control system for a BTT-90 missile and non-linear digital simulations are performed.The results of simulations show that the desired tactical performances for the BTT-90 missile have been achieved.
