| 摘 要： | 为提高运动载体上光电跟踪伺服系统的抑制扰动能力,在反馈型扰动观测器基础上提出二重抑制扰动方法。研究了二重抑制扰动的回路结构、输入输出关系以及执行机构饱和情况下的回路输出特性。应用于光电跟踪伺服系统,可提高载体运动情况下的视轴稳定精度。仿真结果表明,在载体做4°/s,频率12rad/s的正弦信号运动情况下视轴稳定精度小于0.02°,比反馈型扰动观测器提高1倍。 |
| 关 键 词： | 二重抑制扰动回路 反馈型扰动观测器 视轴稳定 光电跟踪 |

| Abstract: | A disturb dual rejection circuit was generated base on disturb observer to improve the anti-disturb performance of a electronic optical tracking servo system on a shift carrier.The circuit structure,the circuit input and output relationship and the circuit output characteristic on servo saturation were analyzed.Applied in electronic optical tracking servo system,it improved the line of sight（LOS） stabilized precision.The LOS stabilized precision reached less than 0.02° in a disturb dual rejection circuit,which was one time higher than that of a disturb observer when the carrier moved at a maximum rate of 4°/s angular velocity with a 12 rad/s frequency sinusoidal. |
| Keywords: | disturb dual rejection circuit disturb observer line of sight stabilized electro-optical tracking |
