Improvement of taxing performance for civil airliner by active control
-
摘要: 以机体的垂直加速度和垂直位移为性能指标,通过建立自校正控制起落架的非线性模型和系统的ARMAX模型,应用多步递推预报对控制器进行设计并结合系统结构和参数的辨识,实现了起落架的自校正控制.计算仿真结果表明,此方案有效地提高了民用客机的滑跑性能.Abstract: Based on two performance indexes of vertical acceleration and vertical displacement of body, by the non-linear model of self-tuning of landing gear and the ARAMX model of system, using the design of controller of the multi-step recursive predictor and the identification of the model parameters and system structure, the self-tuning control of landing gear was implemented. The simulation results show that the control scheme can effectively improve the performance of taxing for civil airliner.
