05. Perfect is Impossible

C3 L2 L3 Perfect Js Impassible 1 V1

If we overestimate our mass by some small amount and we have some non-zero acceleration epsilon ( \epsilon ), would the vehicle accelerate upwards or downwards?
SOLUTION: Upwards

L02 03B Perfect Js Impassible 2 V3

We fail to account for the maximum rotational rate of the propellers in our controller.
SOLUTION: Model Error

The "true position" of the vehicle that we feed back into the controller actually isn't exactly right.
SOLUTION: Noise

A sudden gust of wind blows the vehicle off of its intended trajectory.
SOLUTION: Disturbance

We fail to account for slight deviations from the propellers' idealized F = k_f \omega ^2 force profile.
SOLUTION: Model Error
