基于AT89C52和AD2S83的圆感应同步器测角系统

Angle Measurement System of Round Inductosyn Based on AT89C52 and AD2S83

根据圆感应同步器的检测原理,应用单片机和AD2S83对其输出信号进行处理,设计了一套以AT89C52单片机和AD2S83为核心的鉴幅型圆感应同步器测角系统。具体论述了该系统的硬件结构、电路分析以及在减小动态误差方面采取的措施,并且设计了一种高精度、低噪声的前置放大电路提高系统的抗干扰性能。该系统结构简单,工作可靠,抗干扰能力强,同时具有很高的跟踪精度,具有很高的使用价值。

According to the principle of testing of round inductosyn, single-chip microcomputer and AD2S83 were used to process the signal, which was output from round inductosyn. A suit of angle measurement system of amplitude round inductosyn based on AT89C52 microcomputer and AD2S83 was designed. This paper discussed the hardware of the system, the circuit analy- sis and the step that was used to minish ~e dynamic error in detail. And it designed a high precision and low noise preamplifier to improve the system ability of anti-jamming. The system has the specialty in simple structure, working stability, high anti-jamming, high track precision, and it has high utilizable values.
