Test bench calibration of an accelerometer unit with scale factor errors depending on input signal signs

A joint calibration problem is considered for an accelerometer unit and a nominally high precision test bench. In contrast to traditional calibration problem setting, the scale factors are assumed to depend on the signs of input signals. Guaranteeing approach is applied to the estimation problem. An optimal design for calibration is numerically obtained and the corresponding optimal guaranteeing estimates for desired parameters are constructed. Real experiments were carried out jointly with the JSC ASPE ‘Temp-Avia” (Arzamas).
