高准确度转台中动态测角方法的研究

Reseach On Dynamic Goniometry of High-accuracy Motion Simulator

设计了一套用于高准确度转台中动态测角的方案。该方案在输出角位置的同时,在其模拟信号被采样时刻和数据传输结束时刻发出标示信号,从而准确标定每一个角位置产生的时间点与位置值的对应关系,达到对被测试惯性产品动态校准的目的。同时,提出了一种可以进行自校准的设计方法。

The scheme for measurment of high-accuracy motion Simulator＇ dynamic angle is designed. The method gives the angle positions in motion as digital values, and at the same time gives every position＇ s sample time point when it was a analog signal. As a result, every position＇ s generant time point is accurately marked, and these datas can be used for calibrating the dynamic parameter of inertial products. In addifion, a method for self-calibrating is designed.
