摘要
研究了舰载机横侧向着舰控制律。建立了舰尾气流扰动下的舰载机横侧向数学模型;提出了基于滚转角指令控制方式的舰载机横侧向着舰控制律设计思想,并分析了滚转角指令控制方式的优点;采用SHL神经网络动态逆控制方法设计了横侧向着舰控制律;对舰载机滚转角、航迹侧滑角和偏航角进行了数值仿真。结果表明,横侧向滚转角指令控制系统对飞行状态变化具有良好的鲁棒性和解耦能力,对舰尾气流扰动的敏感性远低于滚转角速率指令控制系统,能较好地满足着舰控制要求。
The lateral landing control law of the carrier-based aircraft is studied in this paper.The lateral motion equations in the aircraft carrier＇s disturbances are introduced,and then the principles of roll angle control and roll angle hold are proposed,and also their advantags are analyzed.Furthermore,SHL neutral network control method based on dynamic inversion is applied to design the lateral landing control law.Finally,the numerical simulations of the roll angle,slide track angle,yaw angle are made,and the results indicate that the lateral landing control system has a good robust performance and decoupling capacity,and is less sensitive to the disturbances than the system based on roll rate,and meets the demand of landing magnificently.
