Model: github.com/Vinayak-D/GNCAirst...
In this video you will learn how to build a complete guidance, navigation and control (GNC) system for a rocket / missile which is commanded to reach a specified target starting from a random initial position, by using LQR /LQG and Kalman filtering methods for control and estimation. You will learn
1) How to calculate azimuth, latitude, and longitudes
2) Calculate guidance commands, range, miss distance, elevation
3) Design Linear Quadratic Regulator / Gaussian (LQR) for a 2d state space model
4) Build a 3-DOF Simulation with the Aerospace Blockset provided within Simulink
5) Perform simulation with FlightGear

I very much enjoyed this video! Although it took me a while, I was eventually able to get a valid result using this method! However, there is something crucial that stumped me for a while. At 19:24 in the video, you enter the earth's radius in Km. I followed along (not thinking too much of it) and I kept getting invalid results for example I would get a warning flag from the start. But then when I worked back through the model/code and did a bit of manual calculation I found that using the Haversine formula you spoke about, my horizontal distance was ridiculously small, hence why I was getting a warning flag from the beginning of the simulation. So I used meters rather than Kilometres and this fixed the issues I was having. Although I will say, that troubleshooting this problem really did aid my understanding of the full system! So there is a bright side haha. By the way, if what I have said is incorrect, please do let me know. I always like to learn even if it means I am wrong. TLDR: If you are following along and getting invalid results make sure you use meters for the earth's radius (at 19:24) and not kilometres.

Hey Vinayak, I am currently working on a project where I have to connect FG to Matlab/ Simulink. Your videos have been pretty helpful so far, but I was wondering if you have ever tried to connect two instances of FG to the same Simulink model to perform simultanous flight trajectories of two planes via FG Multiplayer mode. The problem I have is about the communication between the two FG instances since there is always a "jitter" in the visualization instead of a fluent movement. I would be really happy for any advice! Other than that: Keep it up! Your videos are great!

while implementing the guidance model; x and z are they given in terms of theta or gamma? 'cause the formula you showed mentions theta, but your simulink diagram taps gamma. Thank you so much for the effort put in.

@VDEngineering 3 жыл бұрын

Hey, so the true formula is gamma yes, that was a typo. However, if you run this simulation you'll notice that angle of attack stays at 0, which means theta ~= gamma, (because Az ~= 0), so either will give you the same result. Thanks for spotting that!

Thanks for sharing your vids. I think you cover A LOT of VERY interesting topics. However, the reason it's difficult to follow your content is because it always feels like you cram in 5 hours of content into a 20 mins video. As such, if one already was way too familiar with what it is that you are doing, they'd benefit from the quick demonstration. But for those who aren't already very familiar, it doesn't really teach them all that much. But it must take a lot of effort to put all these together. Thanks for taking the time out to do this anyway.
