ABSTRACT:
An improved electronic line shaft provides for a predictor sending predicted position and/or velocity values to servant drives that may be later strobed in by high speed low-latency strobe signals to eliminate network jitter and delay. The predictor may be implemented as a phase lock loop, providing filtering of a master encoder signal together with flexible electronic gear ratio adjustments and other desired control refinements.
