自动着舰的控制构型研究

在参考美军自动着舰系统(ACLS)的基础上,研究工程上最合适的ACLS控制构型。首先,分析了垂直速度指令和俯仰角指令在轨迹控制本质上的不同点和相同点;然后,将上述两种指令控制结构与两种动力补偿系统(速度保持APCS和迎角保持APCS)一对一组合成4种控制构型,仿真比较了这4种构型在指令响应、风扰抑制上的性能差异,分析了其物理原因。结果表明,H·指令加迎角保持APCS的控制构型对飞机纵向控制更有利,特别是对轨迹、高度要求严格的着舰任务。这与美军的实际试飞结论相同。

Study on automatic carrier landing control configuration

On the basis of reference to automatic carrier landing system (ACLS) of the U.S.military,the best appropriate control configuration of ACLS are studied.Firstly,the track control essence in vertical rate command and pitch angle command is compared,and the differentia and sameness is obtained.Then the above two kinds of command control structures and two power compensation systems(APCS) are combined into four kinds of configurations by one to one,the command response performance and wind restraint performance are compared by simulation and physical analysis.It is considered that the configuration using H-dot command and APCS with constant AOA is more advantageous to flight control,especially to carrier landing which has strict requirements for height and track.The results are accordant with the conclusions of U.S.military's carrier landing flight test.
