GyroWheel is an integrated device that can provide three-axis control torques and two-axis angular rate sensing for small spacecrafts. Large tilt angle of its rotor and de-tuned spin rate lead to a complex and non-linear dynamics as well as difficulties in measuring angular rates. In this paper, the problem of angular rate sensing with the GyroWheel is(More)
In this paper, a simplified model of GyroWheel is presented, based on which a novel experiment identification scheme is proposed to identify the model of a kind of two input two output coupling system, such as the transverse-axis dynamic system of GyroWheel. Applying the simplified model and the proposed identification scheme, a nominal model of the(More)
