- The aim of present article is investigating properties of accelerometer calibration method, called automatic calibration. The research of transducer's model was conducted and chosen optimization algorithms were rated by the simulation method and also using real transducer. The aim of tests was examination of the possibility to find parameters of the transducer model considering influence of temperature and deviation of axes. Described optimal calibration process without special calibration apparatus considers also influence of temperature on acceleration measurement. Afterward, described calibration method was tested on real transducer. Obtained results show that the hybrid two-step algorithm is suitable to the multiaxial transducers calibration. In the research, accelerometer as triaxial transducer was chosen and subjected to tests and the results of simulation was recorded in the MATLAB workspace. From existing estimation, three algorithms were chosen: the quasi-Newton, simplex (Nelder-Mead), and Levenberg-Marquard. The experimental part of the calibration utilized the idea of using existing and known constant vector of the measured value like gravitational acceleration and magnetic field. Calibration with temperature compensation of real transducer was presented.
