A low-cost and low-weight attitude estimation system for an autonomous helicopter

摘要

In this paper a low-cost and low-weight attitude estimation system for an autonomous helicopter is presented. The system is based on an inclinometer and a rate gyro. The data coming from the sensors is fused through a complementary filter. In this way the slow dynamics of the inclinometer can be effectively compensated. Tests have shown that a very effective attitude estimation system can be achieved.
