A single control valve is utilized in the slave loop and in the master force feedback loop of the system. Instabilities in the master loop resulting from the high gain required in the slave loop and inherently existing therein in relation to the slave loop are eliminated by utilization of phase lag and phase lead networks in the master loop. Slew error in the system resulting from the use of such networks is minimized by the provision of phase lag and phase lead networks in the slave loop.
