Calibration of an Accelerometer Unit with Asymmetric Models of Readings of Sensors

The problem of simultaneous calibration of an accelerometer unit and a nominally high-precision test bench is considered. In contrast to the traditional formulations of calibration problems, it is assumed that the scale factor errors depend on the signs of the accelerometer input signals. A guaranteed approach is applied to the corresponding estimation problem. The optimal calibration design is obtained numerically, and the optimal guaranteed estimates for the required parameters are constructed.
