Hemispherical resonator gyroscope is one of the vibratory gyroscopes that can work as an angle sensor as well as an angular rate sensor. Vibratory gyroscopes have advantages that it has relatively long operation time since it has no moving part, it has relatively larger measurement range, and so on. These types of gyros are based on the principle of Coriolis effect. To operate the vibratory gyros,...
The momentum transfer control of a rigid spacecraft with two momentum wheel actuators is investigated using feedback linearization technique focusing on very small nutation angle as a performance index. The equations of motion are transformed to a general linearized form by feedback linearization, including a guarantee of internal dynamics stability. It is known that the configuration of inertia properties...
An adaptive feedback linearization technique combined with neural networks is addressed for the momentum transfer control of a torque-free gyrostat with an attached spring-mass-dashpot damper. The input normalization neural network is used to adaptively compensate for the model error uncertainties of a nutation damper as an internal dynamics and avoid the unnecessary assumptions for stability analysis...
