飛行模擬(5~8) X31 dynamics with NDI/Gain Scheduling controller and Maneuver Generator
2015.3.25

本次動態模擬以空想之速度、方向角輸入飛行操作產生器，希望使飛機產生桶滾翻 (Barrel roll) 的動作

(一)使用NDI控制器
飛行操作產生器產生控制指令，交由NDI(非線性動態逆算)控制器產生舵面作動。
結果動作：捅棍翻(?)
註：1/2錄影速度

(二)使用GainScheduling控制器
同(一)控制器之飛行操作產生器控制指令，後面掛的是Gain Scheduling (增益排程)產生舵面作動
結果動作：捅捅捅捅捅捅捅捅捅捅捅捅捅.....(失敗，飛行失控)
註：1/2錄影速度

(三)使用GainScheduling控制器2
重新設計飛行操作產生器控制指令
結果動作：捅棍棍棍棍棍翻.....(詭異路徑)

(三)使用GainScheduling控制器3
重新設計飛行操作產生器控制指令2
結果動作：桶滾翻翻翻翻翻翻翻翻翻翻翻翻.....(一直翻)

Flight Simulation(5~8) X31 dynamics with NDI/Gain Scheduling controller and Maneuver Generator

This dynamic simulation feeds some imaginary speed and direction angle command into the Maneuver Generator, and hope it make a Barrel roll maneuver.

(一)With NDI controller
The commands come out of Maneuver Generator are hand over to a Nonlinear Dynamic Inversion (NDI) controller, create control surface action.
Result Maneuver: bOrrOl roll (?)
Note: 0.5x recording speed

(二)With Gain Scheduling controller
Use the same Maneuver Generator commands as (一), only the controller of the aircraft is replaced with a Gain Scheduling controller, which create control surface action.
Result Maneuver: bOrOlolololololol.... (Failed. Flight lost control)
Note: 0.5x recording speed

(三)With Gain Scheduling controller2
Redesign the commands of Maneuver Generator
Result Maneuver: barrrrrrrrrrrr-roll.....(Weird movement)

(三)With Gain Scheduling controller3
Redesign the commands of Maneuver Generator2
Result Maneuver: barrel-rollrollrollrollrollrollrollroll.....(Keep flipping)
