A high-precision position-based calibration table as the reference for angular accelerometer calibration experiment

With the role of angular accelerometers in future fault-tolerant flight control systems, an in-depth evaluation of their performance then becomes a critical issue from the perspective of control system design. In this paper, a position-based calibration table is utilized to provide a sufficiently accurate angular acceleration reference in the...

Modelling an angular accelerometer using frequency-response measurements

A characterization of an angular accelerometer sensor is performed with a frequency- response experiment. To assess angular accelerometer dynamic properties, a position-based calibration table is utilized to provide the excitation input. The angular accelerometer specifications and calibration table limitations dfine a constrained test envelope...

Motion Simulator 2-Axis Input Design for Angular Accelerometer Calibration

The calibration of Angular Accelerometers requires a controlled test with a known acceleration profile. However, current turn-tables have been designed primarily for generating a constant rotational velocity. To generate a profile with varying angular acceleration we propose using constant rotational velocity on the two axes of a 2-axes motion...
