| 摘 要： | 结合动量定理和动量矩定理分析了X-Y式光电跟踪系统的动力学特性,建立了X-Y式光电跟踪系统的非线性模型,并用虚拟样机技术对其非线性模型进行仿真.理论分析与仿真结果表明,当X轴和Y轴均以较高的角速度或角加速度运动时,因非线性关系所导致的扰动力矩会严重影响系统的跟踪精度,当X-Y式光电跟踪系统的X轴相对其各惯性主轴的转动惯量相等时,可彻底解决X轴与Y轴之间的运动偶合关系.

| Abstract: | Dynamics characteristic of photoelectric tracking system with X-Y gimbal was analyzed by momentum theorem and angular momentum theorem and the nonlinear model was built.The built nonlinear model was simulated with virtual prototype technology.Analysis and simulation prove that disturbing moment induced by nonlinear relation will effect seriously tracking precision when X-axis and Y-axis moves on high angular rate or high angular acceleration;moving coincidence between X-axis and Y-axis can be resolved completely when X-axis has same moment of inertia relative to inertia principal axis of X-axis. |
