Static calibration and decoupling of multidimensional force sensor based on GM(0,N) Model

摘要

For the nulti-dimensional force sensor output coupling problem between dimensions, the static calibration and decoupling methods of multi-dimensional force sensor were proposed based on GM(0,N) model. Based on the self-developed two-dimensional force calibration device, we conducted the calibration experiments of axial force and radial force for the two-dimensional bone force sensor so as to obtain the calibration data. The two-dimensional bone force sensor is analyzed by the GM(0, 2) calibration and decoupling model and the traditional matrix method respectively, contrasting the precisions of two methods. The analysis results show that: the proposed calibration and decoupling method of multi-dimensional force sensor in this paper has higher precision.
