    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.

    摘要: To dissipate hydraulic shock created by the bouncing of an implement (20, 110) mounted on a wheeled vehicle (10, 106), such as a towed tillage implement (110) or the bucket (20) of a vehicle (10), such as a wheel loader, an electronic control valve (40), which supplies hydraulic fluid to the hydraulic actuator (24, 164) that raises and lowers the implement (20, 110), is actively controlled by an electronic controller (58). As the vehicle (10, 106) with an implement (20, 110) is transported at higher speeds, the implement (20, 110) tends to bounce creating pressure spikes in the hydraulic system that raises and lowers the implement (20, 110). The pressure spikes are dissipated by actively generating random or cancelling hydraulic pulses in the hydraulic system.

    摘要: A device for controlling movement of a load suspended by cables from a hook point that is rotatable about a vertical axis and movable translationally along an axis of translation, the movement of rotation generating a first or sway angle of the load relative to the axis of translation. The device calculates the first or sway angle and a speed of the first or sway angle, the only input variables used being the length of the cables, the distance between the axis of rotation and the hook point, and the speed of rotation of the hook point, while the acceleration of the first or sway angle is used as an internal variable.
