摘　　要：基于倾斜转弯导弹的运动学和动力学特性,建立倾斜转弯导弹的弹体模型,根据弹体耦合特点进行解耦分析。针对不同耦合特点,分析了运动学耦合、气动耦合和控制学交叉耦合产生原因,通过仿真阐明了各项耦合对控制系统设计产生的影响。基于BTT快速消侧滑的特点,需重点分析对侧向影响较大的耦合项。研究表明在控制系统设计时应关注运动学耦合和控制学交叉耦合对设计性能的影响,为以后的控制系统设计提供便利。According to kinematics and dynamics characters of bank-to-turn missile,the mathematical model of bank-to-turn missile was built,and the coupling model was decoupled. According to effect of coupling,the influences of kinematic coupling,aerodynamic coupling and cross-coupling control were analyzed,and the causes of the couplings were analyzed. The simulation illustrates influence of various coupling on control system. The influence of the sideslip was analyzed based on the characteristics of BTT. Research shows that the kinematic coupling and the cross-coupling control should be paid more attention for control system design. It is useful for control system design in the future.
