摘　　要：为了解决弹体在大滚转角速度BTT机动情况下通道间交叉耦合控制问题,本文提出了一种解耦补偿控制器设计方法,将耦合干扰量与测量输出量叠加后反馈至自动驾驶仪控制器的输入端,改进了干扰传递函数的零点配置和干扰传递特性,有效抑制了通道间干扰量对输出评价的影响。通过极小化干扰传递函数在系统闭环极点处的传递增益,获得了解耦补偿控制参数的数值解。利用三通道交叉耦合模型对所设计的解耦补偿控制参数进行了数字仿真验证。仿真结果表明,所提出的解耦补偿控制器能够有效抑制弹体偏航通道攻角的峰值,同时也提高了俯仰通道的响应品质。A design method of a compensation decoupling controller applied to the bank-to-turn autopilot is pre-sented for overcoming the cross-coupling disturbance caused by the high rolling angular velocity of the missile body.The zero assignment and the transfer characteristics of the disturbance transfer function are improved in the way that the cross-coupling disturbances are fed back to the input of the controller together with the measured outputs,and then the influence of cross-coupling disturbance on the output evaluation is effectively suppressed.By minimizing the transmission gain of the disturbance transfer function at the closed-loop poles of the system,the numerical solution of the decoupling compensation control parameters is obtained.The simulation verification of the decoupling control parameters is obtained by using the pitch-yaw-roll channel cross coupling model.The simulation results show that the compensation decoupling controller presented in this paper is valid to suppress the peak of the angle of attack in yaw control channel,and to improve the response quality of pitch control channel.
