摘　　要：为实现BTT导弹准确跟踪指令的要求,采用LQG/LTR积分多变量控制方法设计自动驾驶仪。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,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的跟踪指令,鲁棒稳定定性较强,具备一定抵抗通道间耦合的能力。In order to track the command, an integral LQG multivariable control was used during the BTT missile autopilot design. Taking the BTr missile with airplane figure for an example, the lateral-roll coupled and pitch self dynamics model was set up accordiug to the flight coudition. Two autopilots were designed and the simulation was finished. The results show that the system can track the command accurately and has the capacity to reject the coupling.
