摘要

When the position signals from pick-up systems (G1, G2), in particular absolute angle-encoders, are processed at given time-intervals (delta T), sporadic measurement errors can occur. The invention calls for each position measurement to be followed closely in time (delta t) by a second measurement. The second measurement is used as the position measurement if the main measurement proves to be erroneous, i.e. when there is a difference in speed from the previous measurement which would not have been expected from the normal acceleration.
