摘　　要：针对巡飞弹在飞行中存在随机干扰、系统模型误差不确定性和通道间严重耦合等问题,提出一种输入、输出论域自整定的变论域模糊线性自抗扰控制方法。根据巡飞弹的动力学和运动学方程建立模糊线性自抗扰控制器,通过改进设计函数型和模糊规则得到输入、输出论域的伸缩因子,实现论域随误差反馈的伸缩变化,使系统能在不同条件下调节线性自抗扰控制参数。通过Simulink数学仿真结果表明,该控制方法对指令信号的跟踪性能、负载扰动的抗干扰性能以及通道间的解耦性能满足控制要求。Aiming at the problems of random interference,uncertainty of system model error and seri-ous coupling between channels in the flight of loitering munition,a fuzzy linear active disturbance rejection control method with self-tuning input and output universe is proposed.According to the dynamic and kine-matic equations of loitering munition,a fuzzy linear ADRC is established.By improving the design of func-tional input universe expansion factor and fuzzy rule-based output universe expansion factor,the universe can expand and contract with error feedback,so that the system can adjust the linear ADRC parameters under different conditions.The results of mathematical simulation show that the tracking performance,anti-interference and decoupling performance of this control method meet the control requirements.
