| Abstract: |
| To solve the problem of low test intelligence and low integration measurement of traditional UAV mass properties measuring method, a high precision measuring method is designed in this paper. The method is sectional calibration in the measuring system, and it automatically selects calibration coefficients according to the different levels, correcting the measuring coefficients, in order to eliminate the nonlinear error of the system. The equipment has the attitude adjustment device, matches multiple interfaces of several UAV types, realizes UAV bidirectional attitude adjustment of pitching and rolling between -10° and 10°, at the same time by integrated algorithm, it can realize integrated solution of mass, center of gravity, and moment of inertia. By the actual tests, its mass measurement accuracy is better than 0.03%, its gravity measurement accuracy is better than 0.163kg?m, its moment of inertia measurement accuracy is better than 0.25%. |
