Cool to see the author did F1Tenth (on his projects page). Great project with lots of material on the web for anyone motivated to build a self driving RC race car.
Early in the article it introduces the A state transition matrix and B the input matrix. What is the intuition of those matrices and where do you get them from? It seems to assume a background in Optimal Control.
The article would be better if it explained those matrixes A and B more in detail with a few simple examples. (maybe it did, but I stopped reading after that, since it builds on top of those undefined concepts)
Can anyone more familiar with control theory recommend some simple projects / applications / simulations that might help learn more about this field? I've been interested in control theory for a while and I have a rough understanding of the math involved, but I feel like I need to tinker with something to really understand it!
