为了给BTT导弹设计出较好结构和性能的自动驾驶仪,基于线性化解耦后的BTT导弹模型,采用线性二次型最优控制方法(LQR),先确定三个通道自动驾驶仪响应时间比值,然后对BTT导弹的俯仰、偏航通道分别采用线性二次型方法进行过载自动驾驶仪的设计。各通道设计完成后引入各耦合项,对设计的三通道驾驶仪进行仿真,结果表明设计的自动驾驶仪有较好的指令跟踪能力,对通道间的耦合有一定抑制能力。

In order to design a bank-to-turn missile autopilot with better structure and performance, a linear quadratic regulator controller was used to determine three channels response time ratio based on a linear and decoupled bank-to-turn missile model. And then it was applied to design pitch and yaw overload autopilots. After three channels design, the coupling is introduced to simulate autopilot to verify the design. The results show that the autopilots have a good ability of tracing commands and had a capability of resistance coupling.
