Hello, I do not have lateral control videos but Stengle has an open online course that may cover it. You can access it at www.learngandc.com. Navigate to Resources/Courses then scroll down. Thanks for watching.
Video frames are created in Octave then processed into videos with ffmpeg. It's all assembled in PowerPoint with the correct transitions and animations to make it flow smoothly.
Why not feed forward a velocity command correction from the glideslope loop? In theory, this could eliminate much of the velocity transient caused by glideslope tracking.
Seems reasonable. How could we create that correction? Thinking on it further, one could identify the glide slope (GS) closed loop TF for VT/Xcmd with the full longitudinal dynamics are in the loop, where Xcmd is GS command. This would capture the expected VT transient due to GS tracking, which could be added to VT command. Is this what you are thinking?
@@LearnGandCpretty much. With a small angle approximation, the additional longitudinal acceleration from a pitch maneuver of delta_theta would just be -g*delta_theta. If we had an acceleration controller, perhaps we could add a straightforward acceleration feedforward of + g*(theta_cmd - theta) = g*e_theta. Without an explicit longitudinal acceleration controller in the loop it's less clear, to your point we'd need to model more dynamics to get it to become a valid Tcmd.
do you have any videos or know of resources on the lateral component (localizer)?

@@LearnGandC thank you!
Phenomenal as usual. What are you using for the animated graphs, Manim tool ?

@@LearnGandCThank you, that's innovative.
