摘要
转台动态精度对整个仿真试验方案拟订和结果评估都是1个重要问题。依据转台动态误差一般理论,给出了典型转台控制系统动态精度模型一般建立方法。在转台输入正弦测试信号下,通过对测试数据的相关分析处理,得到转台动态精度模型的具体建立方法。最后用理论计算结果和实测数据进行比较,得出转台动态精度模型可以用来计算转台动态精度,对仿真试验的设计和试验数据处理都有积极的意义。
The dynamic precision of a rotating platform is key problem to the making of a simulation testing plan and the assessment of the simulation testing results. A common construction method of the dynamic precision model of a typical control system is proposed based on the general theory on dynamic error of the rotating platform. The specific construction method of the dynamic precision model of the rotating platform is obtained by inputting sine testing signals and analyzing and processing the testing results. The comparison between theoretical calculation results and the actually acquired testing data proves that the dynamic precision model can be used to calculate the dynamic precision of the rotating platform,which is highly conducive to the design of the simulation testing and the processing of the testing data.
