Synchronisation device for free-running phase regulation circuit - has phase angle corrected for transmission path delay

摘要

The synchronisation device provides a required phase angle value (theta 2) from a phase angle value (theta) and its first differential (omega), transmitted over a relatively long transmission path. The required phase angle value (theta 2) and the transmitted phase angle value (theta) are used to obtain a delay value corresponding to the transmission time of the transmission path, which can be added to the phase angle value (theta), to provide a time corrected phase angle values (theta 2) which is then transmitted.
