    摘要： A control circuit for stopping a spindle at a predetermined rotational position, of the type having a position sensor for producing a zero volt signal when a specified point on the spindle arrives at the predetermined rotational position, and for producing a voltage which is positive or negative when the specified point on the spindle is in the vicinity of the predetermined rotational position on either the left or right side thereof. The control circuit includes an orientation control circuit for stopping the spindle drive motor when the output signal from the position sensor attains the value of zero volts, thereby stopping the specified point on the spindle at the predetermined rotational position. The control circuit further includes a position adjustment circuit for adjusting the rotational position, of the specified point on the spindle, at which the output signal from the position sensor crosses the zero volt line. The position at which the specified point is stopped is adjusted by the position adjustment circuit, so that it is possible to correct an error in the stopping position which results from a position sensor mounting error.

    摘要： In an controller for effecting bumpless switching between the manual control operation and the automatic control operation there are provided an input impedance connected to receive a measured signal from a processing system, an operational amplifier to provide an output signal to a load, a transfer switch connected between the input impedance circuit and the operation amplifier, a feedback capacitor for the operational amplifier to store a voltage related to the output signal, and a manual setter including means to modify the voltage stored in the feedback capacitor by an external signal. During the automatic adjusting operation the transfer switch is operated to connect the input impedance circuit to the input terminal of the operation amplifier whereas during the control operation by the external signal the transfer switch is operated to disconnect the input impedance circuit from the operational amplifier thus modifying the voltage stored in the feedback capacitor by the signal supplied by the manual controller.

    摘要： A rotatable member, such as a turret at a weapons station, is controllable about an azimuth axis. A weapon is carried in the turret with the weapon being controllable therewithin about an elevation axis. The moments of inertia of the turret and weapon about the azimuth axis and of the weapon about the elevation axis are relatively high. The disclosed system provides for elevation and azimuth control through elevation and azimuth drive trains having reflected drive train inertias which are at least two orders of magnitude smaller than the inertia of the turret and weapon about the azimuth axis and at least one order of magnitude smaller than the inertia of the weapon about the elevation axis. Further, the system senses spurious torque applied about either axis, as for example due to the recoil of the fixed weapon, and provides automatic repositioning of the controlled members about either axis to compensate for angular displacement caused by the spurious torque.

    摘要： A gyroscope unit having a horizontal spin axis hangs from a suspension band within a container. The container is rotatably supported about a vertical axis. A transducer generates a control signal representative of the angular displacement between the gyroscope unit and the container about the vertical axis from a reference position. The container is rotated about the vertical axis responsive to the control signal to reduce the angular displacement from the reference position. A torque about the vertical axis that opposes the angular displacement is directly applied to the gyroscope unit responsive to the control signal. The directly applied torque is a nonlinear function of the angular displacement, being zero below a threshold value of angular displacement and having a predetermined gradient above the threshold value.
