Fuzzy logic denoising of the miniaturized inertial sensors in redundant configurations

摘要

The paper presents a fuzzy logic based algorithm to reduce the noise of the miniaturized inertial sensors used in strap-down inertial navigation systems (SDINS) in linear redundant configurations. The algorithm idea is to establish a weight for each sensor from an SDINS axis (measuring acceleration or angular speed) as a function of the standard deviation of the last m samples acquired from it by using the fuzzy logic techniques.
