摘要 依据天线指向计算、伺服控制等算法,通过MATLAB分别建立天线指向计算中自主推算、直接注入模型、伺服控制中计算速度控制量模型及天线运动方式三种算法验证模型,并对各模型理论模态和实际样例数据进行模态分析。分析结果表示,基于MATLAB建立的天线伺服模型是正确的,天线运动趋势验证方法是可行的。此模型推算结果可有效对算法算例进行佐证,模态分析提供了大量的运动样本数据及相应参数下的天线运动趋势,不仅有利于测试人员更快掌握天线伺服算法理论知识,还能为雷达天线座及伺服系统动态研究提供理论支持。 According to the algorithms of antenna pointing calculation and servo control,three models are established by MATLAB.These three models include autonomous estimation in an-tenna pointing calculation,direct injcction model,spccd control model in scrvo control and an-tenna motion mode.At the same time,the theoretical modal and the actual sample data of each model are analyzed.The analysis results show that the antenna servo model based on MATLAB is correct,and the verification method of antenna motion trend is feasible,The calculation results of this model can effectively support the algorithm examples.Modal analysis provides a large number of motion sample data and antenna motion trend under corresponding parameters,which is not only conducive to testers to master the theoretical knowledge of antenna servo algorithm faster,but also provides theoretical support for the dynamic research of radar antenna pedestal and servo system.
