摘　　要：滚转是导弹突破定向能武器攻击的一种有效手段。滚动通道的主要任务是克服外扰的影响,给弹体提供精确的滚转角速度,这里将通过一个自抗扰控制器(ADRC)实现这一目的。针对俯仰-偏航通道,设计了一个基于定量反馈理论(QFT)的控制器,以克服通道间的运动耦合及参数的大范围变化,准确跟踪姿态指令。数字仿真结果表明,这种复合控制器具有很强的鲁棒性及良好的动态性能。Roll is an effective means to penetrate directed energy weapon＇s attack. The main tasks of the roll channel are to overcome the impact of external interference, and to provide the missile with an accurate roll angular velocity. In this paper, this goal will be achieved through an auto disturbances rejection controller （ADRC）. For the pitch-yaw channel, a controller based on quantitative feedback theory （QFT） is designed to overcome the movement couplings between channels and a wide range of parameter changes, to accurately track attitude commands. Digital simulation results show that the composite controller has strong robustness and good dynamic performance.
