The method and mathematical support for calibration of a goniometric system based on the accelerometers

Abstract

The article is devoted to the development of a calibration method for the goniometric system, which includes accelerometers. The complexity of the technological process of mechanical calibration of accelerometers was noted. It is proposed to apply software-algorithmic correction of measurement results. A mathematical model of signals of an accelerometer converter is described, which takes into account the influence of measurement errors. It is noted that in order to find the parameters of the mathematical model of an accelerometer signal, it is necessary to perform calibration. A mathematical model and the principle of calibration of the misalignment angle of the axes of the accelerometer are proposed and described. To evaluate the effectiveness of the proposed calibration method, experimental studies and data processing of the accelerometer were carried. As a result of experimental studies, an estimation of the degree of error compensation of the ADIS 16534 accelerometer measurements was performed with the application of the modified multi-position calibration method and the calibration method proposed by the authors of this article.
