Aircraft Motion Estimation under Conditions of Uncertainty

The work deals with application of the interval analysis methods
to the outer estimation of the current set of states (geometrical coordinates and velocities) of aircraft, which motion is described by the standard system of ordinary differential equations of the sixth order with known geometric restrictions onto controls in the longitudinal, vertical, and lateral accelerations; the current aircraft controls are not known for the observer. Estimation is performed under conditions of uncertainty about both measuring errors restricted on modulus and the chaotic disturbances that are unknown on the sign and value. The result of estimation is represented by the six--dimensional parallelepiped composed of interval estimates on each of the phase coordinates computed by
special sequential procedures.
