Miniature Rotorcraft Flight Control Stabilization System

Abstract

Attitude determination algorithms for a small rotorcraft are proposed and compared. The first algorithm is based on the well known QUEST algorithm used for spacecraft and satellites Due to large vibration in sensors a pseudo-measurement is developed from gyroscope measurements and rotational kinematics. The pseudo-measurement is used within QUEST to smooth attitude estimations A second simple gyro-compensated tilt sensor and compass is proposed and compared to the optimal QUEST solution. Both algorithms are shown to have similar performance. The simple gyro-compensated tilt sensor and compass is demonstrated on a small autonomous hovering rotorcraft.
