paper following car

lead-lag control so a small car could track a line on paper with minimal oscillation.

modeled the uncompensated line-following car, designed a compensator to cut oscillation and path error, and implemented it on the real hardware. the result was a tuned lead-lag controller that tracked cleanly without the sideways wobble you get when gains are too eager or phase is wrong.
