Abstract

The optical inertial reference unit (OIRU) can provide a reference beam for the line-of-sight stabilization system to achieve precise pointing and tracking. Inertial sensors are mounted to the OIRU platform to provide feedback of angular motions being experienced by the reference beam. However, disturbances and noises existing in the OIRU system will inevitably prevent the reference beam be stabilized within microradian. In this paper, an improved noise reduction disturbance observer (IMNRDOB) is proposed to enhance the disturbance suppression performance of the OIRU. Simulations results verify the effectiveness and experiments data show the disturbance is suppressed by 88.60% with the proposed method.
