High-Precision Disturbance Compensation for a Three-Axis Gyro-stabilized Camera Mount

ABSTRACT:

This paper presents a compound control strategy for prime-precision disturbance compensation in order to improve control accuracy of a three-axis gyro-stabilized camera mount. The influences of unknown disturbances are initial analyzed, and the structural properties of the disturbances are given. For these disturbances that may be described by an exosystem, the internal model principle-primarily based controllers are designed to eliminate the influences. For others, a general polynomial function is employed to approximate them and a quite proportional multiple-integral observer-based mostly management method is adopted to estimate and compensate them. Finally, to verify the effectiveness and superiority of the compound control strategy, comparative experiments between the traditional methods and also the proposed one have been dole out. Experiments with the proposed methodology demonstrate stronger disturbance rejection capability and better steady accuracy.
