Abstract: PROBLEM TO BE SOLVED: To stabilize a boring rod on a device which cuts a work piece by applying a cutting chip supported on the boring rod to the surface of the rotating work piece. SOLUTION: This method is proyided with an error sensor 75 which detects the motion of the boring rod 30 in its normal direction (perpendicular to the surface of the work piece 55 at the point where the cutting chip 40 comes into contact with the surface of the work piece 55) and an error sensor 80 which detects the motion of the boring rod 30 in its tangential direction (parallel to the direction of the motion of the surface of the work piece 55 at the contact point). Further, the method is provided with a means which generates a reference signal corresponding to the signal from the error sensor and an adaptive filter which operates corresponding to the signals from the error sensor and reference signal generating means. A generalized force derived from the correction signal outputted by the adaptive filter is applied to the boring rod 30, which is stabilized.

Abstract: A method and apparatus are provided for stabilizing at least one element of a mechanical system against echo-like responses to mechanical disturbances. One or more error signals are provided by sensing the motion of the system at one or more points. At least one adaptive filter is operated in response to the error signal or signals, and in response to at least one non-advanced reference signal that is directly related to some motion of the system. The adaptive filter produces a corrective signal for driving a mechanical actuator, thereby to apply to the element a stabilizing generalized force. By non-advanced is meant that there is a zero or negative time-delay between the presence of a given signal at the reference-sensing location and the arrival of the same, or a similar, signal at the error-sensing location. In particular embodiments of the invention, the reference-sensing location is the same as the error-sensing location.

Abstract: Se proporciona un método y aparato para estabilizar al menos un elemento de un sistema mecánico contra respuestas similares a ecos a perturbaciones mecánicas. Una o más señales de error son proporcionados detectando el movimiento del sistema en uno o más puntos. Al menos un filtro adaptable se opera en respuesta a las señales o señales de error, y en respuesta a al menos una señal de referencia no anticipada que está directamente relacionado con algun movimiento del sistema. El filtro adaptable produce una señal correctiva para accionar un dispositivo de accionamiento mecánico, aplicando por lo tanto al elemento una fuerza generalizada, estabilizadora. Por no anticipada se entiende que existe un punto de retraso de cero o negativo entre la presencia de una señal dada y el lugar de deteccion de referencia y el arribo de una señal, o una similar, en el lugar de deteccion del error. En las modalidades particulares de la invencion, el lugar de deteccion de referencia es el mismo que el lugar de deteccion del error.
