If you go to thrustcurve.org and look through the lists of motors for
ones with more than 4 files, those are typically ones with more than
one run's data. Which could give you a basis for simulating variation
in real motors. Here's one set, for example:

I'm interested in using state-space tracking techniques to try to improve
position tracking for a rocket, but I need a process model for the motor.
I have the manufacturer thrust curve and a measure of variability, but
modeling the variability as noise doesn't really make sense because thrust
from moment to moment shouldn't be statistically independent of the previous
moment, it should be roughly the same and change only slowly.
What kind of model might be appropriate?
