BTT Autopilot Design and Simulation for Loiter Attack Missile

对巡航飞行BTT导弹,采用侧向过载反馈的协调转弯方式进行自动驾驶仪设计。根据巡航飞行导弹的气动特点建立了BTT导弹的数学模型,并以某BTT导弹为例,分别设计了俯仰、偏航、滚转通道自动驾驶仪,对设计结果进行六自由度仿真。在仿真过程中,对各种耦合项进行检验,结果表明运动学耦合对BTT自动驾驶仪性能影响最为严重。

The BTT autopilot of loiter attack missile has been designed using the lateral accelerate feedback coordination method. ＇Fake loiter attack missile for example; the model has been founded according to the characteristic of the BTT missile aerodynamic. The autopilot of pitch, yaw and roll were designed and the simulation had been finished. During the simulation all kinds of the coupling were introduced into the model, among these the inertia coupling does seriously harm to the performance of the BTT autopilot.
