摘要
纵向引导控制律是舰载飞机自动着舰控制系统的核心。舰载飞机着舰环境存在极大的随机性,舰尾流和航母运动不断变化,传统PID纵向引导控制器因其控制器参数固定不变而缺乏灵活性和精确性。在传统的舰载飞机自动着舰PID控制器中引入模糊控制模块,构造模糊PID控制器,并依据飞行控制工程专家的经验构建模糊规则,可实现根据系统状况对控制器的参数进行在线最优调节。与传统PID控制器相比,可极大地提高舰载飞机着舰飞行轨迹精度,也一定程度改善了着舰飞行控制系统的鲁棒性。以F/A-18A为例进行自动着舰飞行仿真,结果表明应用模糊控制技术可以减小着舰误差,提高着舰品质。
The longitudinal guide control law is the core of Automatic Carrier Landing System（ACLS）.For the uncertain impact of ship air wake and carrier motion to the landing process,the traditional longitudinal PID controller with fixed parameters lacks flexibility and accuracy.Introducing fuzzy logic control module into the traditional PID controller and based on the experience of Flight control experts to build the fuzzy rules,the designed fuzzy PID controller can regulate the parameters of controller online optimally,which can improve the carrier-based aircraft landing trajectory accuracy and the robustness of landing control system greatly.The simulation of F/A-18A landing process shows the fuzzy PID controller can reduce the aircraft＇s landing error and improve the landing quality.
