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?
