BTT导弹自动驾驶仪的积分LQG控制设计

BTT Missile Autopilot Design Using Integral LQG Control

为实现BTT导弹准确跟踪指令的要求,将LQG积分多变量控制应用于BTT导弹的自动驾驶仪设计中。以某飞机型BTT导弹为例,根据其气动特点建立了俯仰独立、偏航-滚转耦合的气动模型,并分别设计了俯仰及偏航-滚转通道自动驾驶仪,对设计结果进行仿真。仿真表明所设计的自动驾驶仪能够很好地跟踪指令,且具有一定的抗噪声干扰能力。

In order to track the command input, the integral LQG multivariable control is used in the BTT missile autopilot design. Take the BTT missile with airplane figure for example, the lateral-roll coupled and pitch self dynamics model was set Up according to the flight condition. Two autopilots were designed and the simulation had been finished. The results showed that the system can track the command accurately and has the capacity to reject noise disturbance.
