Aiming at the phenomenon of poor precision locking motor control executed by the photoelectric encoder of low resolution, a method of gyro locking control based on filtering estimation is proposed. The influence of control precision on self-calibration and coarse alignment of the rotational inertial navigation system (RINS) is analyzed. The model of the control system is established and simulated. Then the control mode is applied on RINS. The results of simulation and experiments show that the precision of locking control method designed in this paper outperforms the previous scheme and the self-calibration effect of RINS has significantly improved.
