High accuracy tracking technology and its application in ship-borne electro-optical system

The critical design for the control system of shipborne electrooptical equipment is how to isolate external disturbance and reduce the dynamic lag error. Several kinds of gyroscope inertial stabilization technology are described and their comparison is made. The investigation indicates that gyroscope feedback loop with higher measurement bandwidth can effectively enhance the system′s disturbance isolation capability, and the formula for calculating system disturbance isolation capability is derived. The principle of computer auxiliary tracking technology is elaborated. The application of gyroscope stabilizationbased computer auxiliary tracking in shipborne electrooptical system is described. The experimental data are given to prove the validity and effectiveness of this integrated control technology.
