Hi all, I have been testing some of Project Chrono's features with their vehicle module and I was curious if anyone can explain this abnormality.
I created a file that creates a PathFollowerDriver component on the M113 tracked vehicle to test how the PID controller works. I started with a straight line path first and was able to get some pretty solid results with the chosen gains. When I transitioned the same gains to a more complicated path (the Double Lane Change Path) the previous gains that I had were too harsh and veered the M113 off of the desired path. Comparing that to the wheeled vehicle, no matter the maneuver chosen, the same gains can be used and the wheeled vehicle would be able to follow the path from beginning to end with little difficulty. My first thought as to why this may be happening is because of the time step difference in simulations (2e-3 in the wheeled vs. 5e-4 in the tracked), but I was wondering if anyone else may have some thoughts behind what may be going on.
