    摘要： A control circuit optimizes the track seeking operation of a disk drive by automatically adjusting the phase margin of a compensator circuit that generates a control signal used to drive the actuator of the disk drive to optimize the actual performance of the drive during track seeking operations. Parametric values of coefficients associated with the compensation circuit used for driving the head of the disk drive are adjusted responsive to the determination of the system phase margin to change the phase margin and bring it within a desired range. More specifically, the present invention provides a method and apparatus for automatically controlling the phase margin in a compensation control circuit for a disk drive having a head driven by an actuator. The head is driven with a control signal that is generated by a compensator circuit. Feedback from the head is employed to create a position signal, which is used to generate a position error signal. The position error signal is combined with a disturbance signal of predetermined frequency. The resulting signal is fed into the compensator circuit, which has a transfer function that can be expressed mathematically in terms of one or more coefficients. The phase margin of the system is computed by taking the phase difference between the disturbance signal and the component of the position error signal that has the same frequency as the disturbance signal. The values of the compensator circuit coefficient are adjusted to bring the phase margin within an acceptable range.

    摘要： The position of the power output member of a motor actuator which is normally controlled by a microprocessor in response to system-supplied condition signals may be set manually by providing a manually controlled selector signal to the microprocessor allowing manually controlled adjustment signals rather than the normal condition signals to form the parameters from which is derived the motor control signal. In the preferred embodiment, a first switch generates the selector signal and a second switch generates the adjustment signal. Such apparatus allows a repairer or installer to adjust a mechanical positioning system driven by the motor actuator while the positioning system is in a variety of precisely selected positions. This control system contains a feature allowing one to change position of the motor actuator's power output member either continuously or incrementally by appropriately manipulating the switch which generates the adjustment signal.

    摘要： An apparatus and method is disclosed for controlling a motor of a machine to move a member at a predetermined velocity. Specifically, a gain factor included in generating a velocity command signal to the motor is dynamically adjustable in accordance with a relationship between the actual following error of the member and the desired following error at the commanded velocity to thereby compensate for drifts in the drive system electronics. The gain factor for a plurality of members may be similarly dynamically adjusted whereby the path of an application point coupled to all the members is accurately controlled. The invention is also suitable for controlling movement of distal ends of a gantry to eliminate or reduce skewing of the gantry member.

    摘要： The invention relates to a remotely-operable remote handling arrangement use in radioactively loaded large-area cells of facilities containing process equipment for reprocessing irradiated nuclear fuels. The remote handling apparatus has an industrial robot which is controlled by a process computer and which, for the purpose of detecting the position of an arm of an articulated joint of the robot, is provided with a rotary sensor for determining the angular position of the arm. The rotary sensor is configured as a resolver and is configured pursuant to the induction principle. A second resolver is arranged coaxially with respect to the first resolver in order to be able to check the true position of the arm of the joint. On its shaft, the second resolver has a suitable indicator which is rotatable with the shaft relative to a zero mark. The true position of the shaft of the first resolver and thus the true position of the monitored arm is detected by a scan from the zero mark to an indicator on the shaft of the first-mentioned resolver.

    摘要： An improved household type sewing machine having a needle bar and a feed dog wherein an actuator adjusts the transverse position of the needle bar and the positional displacement of the feed dog in response to control signals provided thereto, in which a microcomputer integrated circuit is provided for controlling the machine in response to keyboard selectable pattern and control information stored in a static memory which is interchangeable with other memory configurations to provide different patterns, such as alphabetic stitch patterns. The keyboard contains a numeric display with each of the patterns having a corresponding numeric equivalent which is displayed on the keyboard to indicate which pattern is selected. The microcomputer is capable of selectively controllably functionally operating on the stored stitch pattern data in response to input control signals from the keyboard for controllably redefining the stored stitch pattern data to selectively create output control signals for the actuator different from the output control signals corresponding to any one of the stored stitch patterns whereby the position of the stitch forming instrumentalities may be selectively varied to redefine a stitch pattern arrangement different from any one of the stored stitch patterns. Thus, for example, a constant stitch density may be maintained for a selected pattern as the length of the pattern is varied by the operator in such a manner that the selected stitch pattern shape may be maintained.
