Abstract

This paper proposes a more generic approach for flight motion controlling using measure information from baro-inertial system. In particular, we show how to estimate the individual and the accumulated influences of every measurement error on the accuracy of flight control, which cannot be completely compensated by an onboard computational algorithm. We create a program to simulate the flight motion under turbulent atmosphere in a non-inertial system of coordinates. Subsequently, a control system simulator is created based on an optimal controlling algorithm automatically looking for the requested motion trajectory and the controlling rules. This simulator also deploys an algorithm for aircraft stabilization and balancing. Finally, we create a simulation to estimate the measures from gyro-inertial system and barometer.
