    摘要: The present invention concerns a method for detecting a mechanical end stop of a motion system comprising a base designed to receive a motion stage for an equipment, a machine frame resting on the floor and an active isolation system therebetween, wherein said active isolation system comprises several actuators arranged to impart a six degree-of-freedom (DOF) motion to said base, several inertial sensors arranged to provide a six DOF measurement of the base's motion, and dampers to support the base, the mechanical end stop being arranged to limit the base's motion relative to the machine frame, the method comprising the steps of:
    (a) selecting a translational DOF among the six DOFs;
    (b) determining, using the process sensitivity matrix of the mechanical system comprising the base and the active isolation system, a force to be applied to the base by the actuators to cause an oscillatory motion of the base in the selected translational DOF the motion being of a predetermined amplitude;
    (c) applying the force to the base using the actuators to obtain the oscillatory motion of the base in the selected translational DOF;
    (d) detecting a mechanical contact between the base and the mechanical end stop using at least one inertial sensor from the several inertial sensors.

    摘要: A system for infrasonic pressure fluctuation (infrasound) control of a structure defining an interior. The system includes a reversible compressor including a housing defining an interior opening interface open to the interior of the structure and an exterior opening interface open to an exterior of the structure, and including at least one controllable element to generate positive pressure flows and negative pressure flows between the interior opening interface and the exterior opening interface. The system includes a first pressure sensor located to sense pressure indicative of the interior of the structure, a second pressure sensor located to sense pressure indicative of the exterior of the structure, and at least one controller configured to control the at least one controllable element of the compressor to cancel pressure oscillations within the interior of the structure based on the pressures detected by the first pressure sensor and the second pressure sensor.

    摘要: A handling system comprises a container bridge (1), which is arranged on a substrate (3), and at least one load handling point (10, 11) which is arranged on the substrate (3). The container bridge (1) has a trolley (6) which can be moved on a crossmember (5) of the container bridge (1) relative to the substrate (3). A crane controller (12) matches a target location (xK) of the trolley (6), which target location is related to the crossmember (5), and a target location (xL) of the load handling point (10, 11), which target location is related to the substrate (3), to one another in such a way that, when the target load (8) is lowered at the target location (xK) of the trolley (6), the target load (8) is lowered onto the target location (xL) of the load handling point (10, 11). The matching is performed while additionally taking into account at least one target load (L) with which the trolley (6) is loaded at its target location (xK). The crane controller (12) positions the trolley (6) at its target location (xL). Furthermore, said crane controller, after positioning the trolley (6), lowers the target load (8) onto the load handling point (10, 11). If the load handling point (11) on the substrate (3) can be moved and the load handling point (11) is controlled by the crane controller (12), the crane controller (12) further positions the load handling point (11) at its target location (xL) before lowering the target load (8) onto the load handling point (11).

    摘要: A rotational signal of a generation source of a control object is detected and, when a rotational speed (frequency) varies, convergence values of filter coefficients of adaptive filters 33, 34 based on a previous control result corresponding to the frequency stored in a control device 11 are retrieved and set to the adaptive filters 33, 34 as initial values. The adaptive filters 33, 34 are updated by using the initial values of filter coefficients and output a control signal y(t) to an ACM (actuator) 3a. LMS arithmetic units 37, 39 read a reference signal calculated from the rotational signal and an acceleration signal (error signal) e(t) detected by a sensor 9 and carry out processing for updating the filter coefficients of the adaptive filters 33, 34. The adaptive filters 33, 34, based on updated filter coefficients, output the control signal y(t) to the ACM 3a.
