Abstract:
A method and system is provided for estimating and compensating for gyro bias in gyro-stabilized systems. The method includes comparing an output of a gyroscope to a reference measurement; estimating a bias of the gyroscope based on the comparison using a Kalman filter; and adjusting a control output of the gyro-stabilized system with the estimated bias to maintain a position of the gyro-stabilized system.
