Abstract
A method for calibrating an acceleration sensor coupled to a machine may comprise: at a first position of a linkage of the machine, obtaining a first acceleration measurement from the acceleration sensor and obtaining from an input a first force value indicative of a first force on the linkage; at a second position of the linkage of the machine, obtaining a second acceleration measurement from the acceleration sensor and obtaining from the input a second force value indicative of a second force on the linkage; determining a rotational offset calibration value of the acceleration sensor as a function of the first acceleration measurement, the first force value, the second acceleration measurement, and the second force value; and using the rotational offset calibration value to calibrate the acceleration sensor.
