一种船用跟踪设备视轴稳定方法

Research on a Method of the LOS Stabilization of Shipborne ElectroOptical Tracking Equipment

利用坐标变换技术在船用跟踪设备的方位和高低轴上对船摇姿态角进行实时补偿,可以克服船体摇摆对跟踪设备跟踪精度的影响,最终实现稳定"视轴"的作用。通过理论分析,给出了一种由于船体摇摆引起的视轴附加角速度公式,设计了能够较好地解决船摇隔离度问题的伺服控制系统。

The tracking precision of shipborne electrooptical trackers is influenced by the rock interference of the ship. This problem can be resolved by compensating with real time attitude angles of the swinging ship on the azimuth and the elevating axis of the OE tracking equipment with coordinate transformation technology. Then the stabilization of LOS can be obtained. The expressions of LOS angle velocity aroused by the rock interference of ship is introduced through theoretical analysis. Also presented is the design of a servo control system in which the degree of isolating of the rock interference is solved with satisfactory.
