| Abstract: | In order to solve the problem of the transfer alignment method of miniature missiles when applied to a light Unmanned Aerial Vehicle (UAV), this paper analyzes the transfer alignment method based on the modified attitude matching, constructs the attitude error equation, attitude matrix matching equation, establishes mathematical models of both attitude matrix small angle extraction and transfer alignment filters, and completes the numerical simulation. The results show that the transfer alignment method based on the modified attitude matching is suitable for estimating the misalignment angle error and the installation angle error when the UAV is performing both 2 axis and 3 axis attitude swing maneuver in time sharing. In this process, the estimated error is within 5β, and the algorithm convergence time is not more than 10 seconds, which lays a good foundation for the development of light and small UAVs. |
