    摘要: A method and apparatus for positioning a housing of an excavator housing. A motor receives pressurized fluid to cause rotation of the excavator housing. A motor position sensor determines the rotational position of the housing and responsively produces a housing position signal. A pressure sensor determines the fluid pressure supplied to the motor and responsively produces a pressure signal. A microprocessor produces a signal indicative of a desired rotational position of the housing. The microprocessor receives the position and pressure signals, and responsively controls fluid to the motor in order to rotate the housing to the desired position.

    摘要: A printing control method and apparatus for combining forms data and printing data to produce and output printing images. Forms data are handled as a group of forms data including a plurality of component data groups forming partial form elements and component placement information groups specifying intra-page positions of components. For form selection, component placement selection information is selected in the printing data. Component placement information selected and indicated by this component placement selection information is used for form generation. If a plurality of components are the same in partial form elements, therefore, a plurality of kinds of forms data can use components in common and are administered by only component placement information specifying intra-page positions of respective components. As for forms data needed at the time of printing, therefore, components of form elements are placed and combined in accordance with the component placement information. Combined forms data thus generated and printing data are converted into printing images and outputted. As a result, there are obtained a printing control method and apparatus in which forms data are administered efficiently and used effectively.

    摘要: A position control system includes a PID controller for generating a current target value of a linear motor from a difference between a positional detected value and a positional command value, and a disturbance observer. The disturbance observer includes a signal processing unit comprising a filter for filtering a torque command value for a motor drive and an input torque estimating filter carrying out estimation for obtaining an estimated input load torque from the detected positional value. An inverse model of a motor torque constant calculates an estimated disturbance load torque from the difference between the filtered torque command value and the estimated input load torque and generates a correction value for the current target value so as to cancel a disturbance torque on the basis of the estimated disturbance load torque being calculated.

    摘要: A servo system for controlling the position of a read/write head over a rotating data disk is disclosed. The servo system includes the addition of a compensation scheme to the feedback loop that causes the open loop gain of the servo to increase only in a very narrow spectrum of its operating bandwidth. In a preferred embodiment, the compensation takes the form of a second order digital filter combined with a proportional-integral-differential phase compensation filter in the feedback loop of an embedded servo system for a digital data disk drive.

    摘要: An apparatus and method for controlling a hydraulically operated construction machine, having a plurality of tandem articulated members which are controlled in a manner that movement of one of the members is controlled in response to movement of another of the members, in order to move the members in a predetermined pattern. The members are controlled in response to the anticipated future movement of the another member. Anticipated future movement of the another member may be determined, for example, as a function of the present position and velocity of the another member and system delay in movement of the another member. Where the another member is controlled manually by an operator control lever coupled with a manual hydraulic control valve, anticipated future movement may be determined by monitoring actuation of the control lever.

    摘要: An automatic offset adjusting apparatus for current detectors in a digital controller for a servo motor is constructed so that, when errors occur in offset correction values due to a temperature change and the like while the servo motor is in operation, an electrical angle detecting unit detects a ripple of the torque of the servo motor, on the basis of a ripple of a torque command value, and detects a first electrical angle, where the torque command value becomes maximum, and a second electrical angle, where the torque command value becomes minimum, based on an electrical angle signal of the servo motor, a judgement unit judges whether or not offset correction errors have occurred on the basis of a difference between the first and second electrical angles, and, if the judgement unit judges that the offset correction errors have occurred, a correction unit adds adjustment values for the offset correction values corresponding to the first electrical angle to the respective offset correction values to update the offset correction values, whereby the correction of the offset correction values is automatically carried out even while the servo motor is in operation, thereby preventing generation of the ripple of the torque of the servo motor.
