Abstract
The rudder order bias integrator of a marine autopilot is reactivated upon substantial completion of a turning maneuver in response to heading error, heading rate and the derivative portion of the rudder order signal. Upon reactivation, the integrator time constant is ramped from a predetermined small value to the normal large time constant of the integrator.
