What is a control system anyway?
OT anecdote<p>If the cruise control in my vehicle is using PID, it still needs some tweaks. It's super aggressive when it's lower by 2pmh and often overshoots.<p>My mom's is horrid: takes forever to get up to speed, then allows downhill drift to drive the vehicle nearly 5mph over the set speed.<p>I feel like this kind of stuff would be fun to tweak in a simulator to help me understand why it doesn't work better, or show that I'm not entirely crazy and it can indeed be improved.
