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 for this particular setup. Measurement are obtained for a number of constant accelerations and varied with frequency. Analysis of the input-output relation in the frequency-domain leads to a frequency-response function model of the angular accelerometer. Time-domain data are used to validate the frequency-response model. A fourth-order structure is then preferred as the transfer-function for the 400 deg=s acceleration, with a 99:02 %fit. Besides representing the angular accelerometer dynamics, the angular accelerometer model is es- sential for the design of fault-tolerant light control system.
