- optimal control.
- separation principle.
- state propagation and state reconstruction.
- model errors ( faulty a priori knowledge ), like the mass of an object.
- unknown "external" inputs, like gusts of wind ( or like friction forces if you don't consider them modelling errors).
- measurement errors.
- one day, put memo PL-00-088 here.
