Study on speed-limit protection for ship-borne servo system's low-elevation tracking

Large-scale The influence factors of ship-borne servo system's low-elevation tracking are analyzed in this paper. The ship-rolling influences the low-elevation tracking most, and the unfit speed-limit will cause tracking lost. By simulating tracking loop, the influence to low-elevation tracking is analyzed. In the end, the thresholds of speed-limit in different states are confirmed.
