| 摘 要： | 针对旋转式感应同步器中零位误差的检测和数据处理工作量大的问题,提出一种以高精度光学分度头作为角度基准的自动测量方法,首先对系统的前置放大器和相移电路进行误差分析,通过合理设计二级运放的增益提高输出信号的信噪比,采用移相网络的方法补偿参考信号与输出电势之间的相移,光学分度头的输出信号和感应同步器输出信号进行比较计算后得到误差信号,在感应同步器连续旋转工作时,实现对其零位误差的动态自动检测.实验结果表明,系统的误差检测精确度为峰-峰值1.1",该方法可以实现旋转式感应同步器零位误差的高精确度检测.

| Abstract: | Zero position error is the main error of rotary inductosyn and the workload of its measurement and data-processing is very heavy.Aiming at this problem,a new automatic measurement method was proposed,which taking high precision optical dividing head as angle benchmark.The errors of preamplifier and phase shift circuit were analyzed firstly,and then the gain of secondary operational amplifier was designed reasonably to reduce signal noise ratio.Phase shift network was used to compensate for phase shifting be... |
