A device for compensating for actuator rate saturation is disclosed by this patent application. The device is an improvement to a servomechanism of the type wherein a command signal and a position feedback signal from a member being positioned are summed to produce an error signal for driving an actuator to position the member in accordance therewith. The improvement is a means for inverting the error signal when the ratio of the slope of the position feedback signal to the slope of the command signal is less than one and the popularity of the error signal is opposite to the polarity of the slope of the command signal, and the absolute value of the error signal is not increasing. Application of the invention to the flight controls of an aircraft is disclosed. jhd
