Analyses of Triaxial Accelerometer Calibration Algorithms

Original language description

This paper describes three tri-axial accelerometer calibration algorithms using mathematical model of nine parameters and the fact that the sum of sensed acceleration should be always equal to gravity vector under stationary conditions. The advantage ofproposed algorithms is that the process does not require precise platform or special calibration equipment. The sensor error model (SEM) of tri-axial accelerometer consists of three scale-factor errors, three non-orthogonality angles, and three offsets.Three different algorithms were tested - Levenberg-Marquardt and Thin-Shell algorithm, and algorithm based on Matlab function fminunc. The proposed calibration process and its algorithms were experimentally verified on five accelerometers. We performed various analyses of proposed algorithms and proved that the proposed algorithms were capable to estimate the parameters of SEM without a need of precise equipment usage, which was the main aim of our investigation.
