中文摘要:

Conventional gyrocompass alignment methods are based on relatively small azimuth misalignment angles.However,a marine strapdown inertial navigation system may face large azimuth misalignment angle caused by a failed coarse alignment algorithm.This paper provides a novel gyrocompass alignment method to solve the problem.Effects of system parameters are analyzed and the proper scenario of parameter switch based on the classic control theories is derived.Test results show that compared with the conventional methods,our method can accomplish the initial alignment quickly and accurately under large azimuth misalignment angle.
