摘　　要：感应同步器、旋转变压器是一类基于电磁感应原理的角位置传感器,广泛应用于自动控制、伺服系统中,其输出信号是一组随角位置变化呈比例关系的交流电压信号。要对该信号实现精密测量或校准需要使用专用角度指示器,此仪器功能单一且价格高昂。因此,使用通用数字化仪研制了一套精密角位置信号数字化测量系统,实现了分辨力达0.0001°,测量准确度达±0.001°(k=2)的同步分解信号测量能力。该系统不仅可应用于角度模拟器、感应同步器、旋转变压器的校准或检测中,相关技术还可以应用于国产化精密角度指示器研制中,具有良好的应用前景。Resolver and synchro are a type of angle position sensors based on electromagnetic induction,which widely used in automatic control or servomechanism.Their output signals are a series of AC voltage signals that change proportionally with the angle position.In order to measure or calibrate these signals,precision angle position indicators(API)are required,which are very expensive with single function.We developed a precision angle position signal digital measurement system based on universal digitizers,and realized resolver and synchro signal measurement with 0.0001°resolution and 0.001°(k=2)uncertainty.The measurement system can be applied in metrology of Resolver/Synchro Simulator or sensors,and related technologies can also be applied in design of domestically precision angle position indicators,has good application prospect.
