Abstract
In a servo loop closure for an aircraft control surface, surface position from the control surface synchro is utilized to augment the servo motor rate feedback so as to reduce limit cycle oscillation. The high frequency content of surface position is suppressed by substituting a percentage of the low frequency content thereof for the same percentage of low frequency servo motor rate. This arrangement reduces control column activity normally associated with high effectiveness ratios of surface position for servo motor rate substitution.
