摘要
为保证快速、有效的激光通信系统数据传输,对数据传输误差成因进行分析。重点分析了由惯性导航系统和定位仪器测量精度差产生的状态误差和定位误差,简要介绍了较正误差、伺服驱动误差和指向误差的成因。由于误差成因种类多且影响程度不一,单项误差控制难以实现,故设计基于模糊逻辑控制技术的激光通信数据传输控制器,以产生误差的激光通信系统测量值为输入值提取控制参数,建立模糊控制规律,并通过实验分析控制器性能。实验结果显示,所设计的控制器响应快,对数据传输误差的控制有效性强。
In order to ensure the rapid and effective laser communication system data transmission error causes are analyzed and emphasically analyzed by inertial navigation system and the positioning instrument. This paper briefly in- troduces the causes of calibration error, servo drive error and error pointing. Due to the errors variety and different de- gree, single error control is difficult to achieve. So the design based on fuzzy logic control technology of laser communi- cation controller was proposed. Treating the measurement value of laser communication system which produces error the input value control parameters, establishing fuzzy control rules, and do the experimental analysis of controller perform- ance. Experimental results show that the designed controller has fast response, high efficient control of the data trans- mission error.
