  • Aircraft autopilot with yaw control by rudder force
    Patent number: 4992713
    Abstract: An autopilot with long term yaw coordination capabilities which utilizes lateral acceleration to generate a rudder force command which is combined with the sensed rudder force to create an error signal which is combined with a rudder servo velocity signal and then integrated to create a virtual rudder position feedback signal for combination with the rudder position commands, generated from yaw rate information.
