High Precision Angular Measuring System Based on Round Inductosyn

In order to measure angle precisely, the angular measuring system that has achieved 16 bit high resolution and outputed digital signal stably is designed and accomplished. According to the working principles of round inductosyn and resolver-digital converter, the external components of the converter AD2S80A are optimized. A high precision and low noise preamplifier is designed for improving the system ability of anti-jamming. It has been proved by the experimental results that the system achieved the design requirements, which angular resolution of display is 0.1" and measuring error of angle is ±0.3".
