基于增量动态逆框架的舰载机直接升力航迹控制

Carrier-based aircraft trajectory control using direct lift based on incremental nonlinear dynamic inversion framework

直接升力在舰载机下滑着舰过程中可以快速修正航迹误差、解耦航迹操纵复杂度。为了使直接升力控制充分实现上述改善效果和控制目标,利用逆反馈控制中的增量动态逆方法搭建了着舰模态控制律基础框架,同时在航迹控制通道上实现了直接升力控制。在数学推导动态逆与增量形式异同的基础上,仿真验证了两种控制框架实现直接升力的有效性。仿真结果表明,在增量动态逆着舰框架上实现的直接升力航迹控制具有更高的鲁棒性。

The direct lift of the carrier-based aircraft landing can quickly correct trajectory errors and decouple manipulation complex.In order to achieve the above advantages of direct lift control,a landing control framework was built by using the incremental dynamic inversion method for inversion feedback control,and the direct lift control in the trajectory control channel was implemented.Meanwhile,the mathematic derivation was accomplished for demonstrating the difference of nonlinear dynamic inversion and incremental nonlinear dynamic inversion,and the simulation verification was executed to certificate the effectiveness of direct lift by two control frameworks.Simulation results show that direct lift trajectory control based on incremental nonlinear dynamic inversion control have more robustness.
