摘要： For topographic processing, a plurality of maps are stored, the maps being of different scales and therefore being based on different amounts of map data. The user selects a map of appropriate scale, and can then select a part, for example a line, on which appropriate analysis is to be made, such as obtaining a cross section based on contour data of the map. The map data corresponding to the selected part of the map is investigated and, where it does not meet an appropriate criterion, the data of a part of a map of different scale is investigated, the part of the two maps corresponding to the same region. Hence information can be derived which meets the appropriate criterion. Thus, when obtaining a cross section, if the amount of data for a region of a map is insufficient for a satisfactory cross section to be obtained, the data of the same region of a map of larger scale is analyzed, so that a satisfactory cross section can be achieved. The processing is also applicable to the investigation of lines of sight, using the map data.

摘要： The invention provides a servomotor control apparatus which performs standard mode-type velocity control. An acceleration signal is formed by a differential computation or difference computation, from a velocity signal fed back from a servomotor. An acceleration value of the servomotor (d) is estimated by a criterion model (2) of a velocity control system utilizing a current command T(S) formed in a velocity control loop. The computed acceleration and the estimated acceleration are compared and the current command T(S) is corrected in conformity with the results of the comparison.

摘要： A servomotor control method controls a servomotor stably at a high speed. A control loop is switched from a PI control mode to an I-p control mode by varying a gain coefficient of a proportional arithmetic unit (1). This achieves a control process having the advantages of both the PI and I-p control modes.

摘要： An apparatus for driving an A.C. motor includes a circuit for computing the sum of polyphase A.C. signals used to drive a pulse-width modulation circuit for controlling an inverter, and for limiting the amplitude of a current command when said sum is other than zero. When an imbalance occurs in the polyphase A.C. signals, the current command amplitude is immediately limited in accordance with the state of the imbalance to prevent saturation of a current amplifier that is operable to produce the polyphase A.C. signals by amplifying the outputs of an arithmetic circuit. These outputs are difference currents obtained by computing the difference between polyphase command currents and corresponding ones of detected polyphase currents actually applied to the A.C. motor. Preventing saturation of the current amplifier assures that the polyphase currents actually applied to the A.C. motor will be held in a balanced state at all times.

摘要： An operation for recording a recording signal onto a disk (1) is interrupted, when an amount of signal data stored in a buffer RAM (11) for temporarily storing the recording signal is less than an interruption setting value during performing of the recording operation. Moreover, when the amount of signal data stored in the buffer RAM (11) increases and indicates a resumption setting value, the signal recorded on the disk (1) before interruption is reproduced, and the recording operation is resumed based on the reproduced signal. Moreover, recording properties are detected by the signal reproduced before resumption of recording.

摘要： A servo motor controlling method for controlling both speed and current of a servo motor under digital control. An integration gain unit (22) and a loop proportional gain unit (26) of the current controlling loop are subjected to correction by respective gain units (23, 27) so as to be increased depending upon the rotational speed of the servo motor. Since a current loop gain is increased depending upon the rotational speed of the servo motor, the oscillation of the current loop does not occur at the time of low speed drive and stop, and the shortage of torque due to the lowering of the current loop gain at the time of high speed drive can be prevented.

摘要： A negative feedback control system includes a step of amplifying digital information by an amplifying operation at a high response speed and not including an integration. The negative feedback control system detects a predetermined amount of increase and decrease in the controlled variable, and outputs an increment signal or a decrement signal according to the predetermined amount of increase and decrease in the controlled variable, respectively, receives increment signals and the decrement signals from a controlled variable detecting unit 4, ignores the first successive n increment signals immediately after an arbitrary decrement signal, then begins to count each increment signal as a +1 unit from the n+1-th increment signal after the arbitrary decrement signal, and ignores the first successive n decrement signals immediately after an arbitrary increment signal, then begins to count each decrement signal as a -1 unit from the n+l-th decrement signal after the arbitrary increment signal (FIG. 2); whereby the vibration of the controlled variable is suppressed.
