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。
Based on the ACLS, the most suitable engineering ACLS control configuration was studied. First of all, the differences and similarities between trajectory control of vertical speed command and pitch angle command are analyzed. Then, the two instruction control structures are compared with two kinds of power compensation systems (speed keeping APCS and angle of attack keeping APCS) A set of four control configurations were synthesized, and the performance differences between the four configurations in terms of command response and wind disturbance suppression were compared and the physical reasons were analyzed. The results show that H · command angle-of-attack keeping APCS control configuration is more beneficial to the longitudinal control of the aircraft, especially for the track, altitude demanding task. This is the same as the actual test flight of the U.S. military.
