摘　　要：研究了小直径炸弹倾斜转弯(BTT)控制系统俯仰/偏航通道的耦合特性及其解耦控制问题.建立了俯仰/偏航通道耦合动力学运动模型,引入相对增益指标,定量分析了小直径炸弹俯仰/偏航通道的耦合特性;利用对角矩阵补偿方法,设计了工程适用的俯仰/偏航运动的解耦补偿控制器.仿真实例表明:系统耦合项增益能得到有效的抑制,所设计的解耦补偿控制器对控制指令的动态跟踪性能良好,为小直径炸弹BTT控制系统的工程应用提供参考.The bank-to-turn（BTT） control system of small diameter bomb（SDB） for pitch/yaw channel coupling characteristics and the decoupling control problem were studied. The coupling motion was modeled, coupling characteristics between pitching and yawing channels was quantitatively analyzed with relative gain index. An engineering-practicable decoupling controller was designed by a diagonal matrixcompensating method. Simulation examples indicate that couple gain after decoupling can be effectively suppressed at all frequency points. The designed decoupling controller can track control command, and it offers reference for BTT control system of SDB.
