Abstract提出一种基于贝叶斯推理估计方法的时间同步抖动修正计算方法,通过已获得的总线传输延时作为采样样本,并通过贝叶斯推理估计,得到经过估计修正的总线传输延时,以提高数控系统现场总线时间同步精度,经过试验测试,提出的同步抖动修正方法能够保证时间同步的同步抖动不大于0.5uS,能够满足高档数控系统高速、精密加工对总线的同步控制需求。
Other AbstractThe jitter correction method based on Bayesian estimation was achieved.By using this method,the transformation delay of field-bus could be estimated with the samples of delay of field-bus.The experiment shows that the synchronization jitter can be reduced to 0.5uS by using the jitter correction method.And high-speed precision processing control needs of CNC can be met by using this method.
