Abstract:

Gyrowheel is always operating at de-tuned spin speed and large tilt angles, which leads to its complicated mechanism and low precision for attitude measurement. To solve this problem, an attitude measurement method is proposed that combines the attitude operating mechanism with the deep neural network-based error compensation. In consideration of the sensor configuration constraints of the gyrowheel system, a mechanism-based measurement model is constructed based on the transverse-axes dynamics through the simplification of assumptions. Besides, a deep learning-based regression model is developed by integrating a long short-term memory network and a dual-channel attention mechanism. It explores the potential relationship between the measurement errors and the operating status of the gyrowheel, yielding the error compensation for the mechanism-based model. On this basis, a hybrid attitude measurement approach is presented, which offers a high-precision way to estimate the external angular velocities of the gyrowheel. The precision improvement and superior performance are verified through comparative experiments.
