摘　　要：飞行控制系统设计是倾斜转弯(BTT)控制型导弹的一项关键技术。BTT导弹转弯和机动时需绕其速度矢量快速滚转,因而会导致较强的俯仰与偏航通道耦合,给飞行控制系统设计带来困难。本文对BTT导弹飞行控制系统进行设计,内回路采用LQR控制方法以抑制系统不确定性;外回路采用混合灵敏度H_∞鲁棒控制方法以抑制外部干扰和消除模型不确定带来的影响。仿真验证表明,所设计的BTT导弹飞行控制系统满足控制性能要求,目标拦截性能优于基于经典控制方法设计的BTT导弹飞行控制系统性能。Flight control system design is a key technique for bank-to-turn （BTT） missile. Because BTT missile needs to spin around its velocity vector rapidly when it makes a turn or maneuver,this will result in stronger coupling between pitch and yaw channels and bring difficulty for the flight control system design. In this paper,a flight control system design is performed for BTT missile,in which,LQR control method is employed in the inner loop to suppress system uncertainty,and the mixed sensitivity 匀肄 control method is used in the outer loop to suppress outside disturbance and eliminate the effect caused by model uncertainty. Simulation results demonstrate that the designed BTT flight control system satisfies the control performance requirements, a n d has better target interception performances c o m p a r e d to the flight control system designed with classic control method.
