| 摘 要： | 基于RTlinux和AD2S80A的角位置测量系统,选用旋转变压器和感应同步器作为测量系统的传感器,利用AD2S80A轴角变换器将两种测量传感器输出的模拟信号转换为相应的数字信号。根据双通道测角系统粗精耦合的原理,在RTLinux嵌入式系统中对两种数字信号进行耦合处理,并对耦合后信号的进行补偿处理,实现角位置的高精度测量。检测数据表明,这种测量系统可以实现以内的测量精度。

| Abstract: | Rotary transformer and inductosyn are chosen as sensors in the angle measuring system which is based on RTLinux and AD2S80A. The resolver-to-digital converter AD2S80A is used to convert analog signal into corresponding digital signal, and the analog signal is generated by the two sensors. Then, digital signal will be combined and compensated in the RTLinux embedded system by the combination for coarse-fine coed principle. Detected data has effectively improved that this measuring system can realize an measuring precision within. |
