摘要
分析常规采样法产生同步误差的原因,阐述了三种通过实时改变采样间隔有效减小同步误差的算法,即偏差累积增量法、采样间隔动态调整算法和实时最佳同步采样算法;分析了这三种改进算法的误差和性能,供交流周期信号测量选择。
The factors that caused the synchronous errors were analysed, three algorithms for software synchronization sampling, including cumulated deviation increment sampling, dynamically adjust sampling period and the best real time synchronization sampling, were explained. The error caused by each algorithm was analysed, and some suggestions for AC periodic signals measurement were provided.
