摘要： A digital servo control system for controlling a drive motor accumulates speed and phase error numbers and produces a pulse width modulated signal in response thereto. Phase errors are measured by counting pulses of a clock signal between the arrival of a position signal related to a rotational position of the drive motor and the arrival of a reference signal. An automatic residual error compensating circuit controls a delay applied to the position signal in accordance with residual phase error to minimize the same.

摘要： A positioning system is provided in which command and feedback signals are processed to develop an analog error signal for application to a servo drive to position a controlled element. The command signals are in the form of pulses each of which corresponds to a certain incremental distance of movement. The feedback signals are developed from phase shifts of a low frequency resolver signal, such phase shifts being proportional to movement of the element. Such feedback signals are applied to a resolver digitizer circuit which develops a train of resolver pulses in response to the phase shift represented by each feedback signal. Each such resolver pulse corresponds to the same incremental distance of movement as a command pulse and both the resolver pulses and the command pulses are applied to a comparator and error signal circuit in which any cumulative error in either direction is stored as a digital number and is converted to an analog error signal of the proper polarity. The system effects accurate positioning of an element while accommodating a large temporary following error and thereby allowing movement at high speeds in response to high command pulse frequencies.

摘要： An optical micrometer scans an article passing through its zone of measurement to provide a series of pulses representing the dimension of an article. Each new measurement is compared against a previous measurement, or an average of a predetermined number of previous measurements, and the difference is then compared to a previously established deviation limit. If this difference does not exceed the deviation limit, then the new measurement is transferred to the output of the circuit for utilization by the system, but if this difference exceeds the deviation limit, then the previous measurement signal will be transferred to the output. An alarm is provided whenever a predetermined number of new measurement signals outside the deviation limit occur within a certain number of measurement intervals.

摘要： A set point adjust mechanism is disclosed for use with process controllers to manually adjust the set point value and simultaneously change the set point value indicated. The set point adjust mechanism includes a manually actuable thumbwheel and an idler wheel mounted in contact with each other on a slider. Thumb pressure on the thumbwheel causes the slider to move so that the idler wheel contacts an indicator drive wheel. The set point value source, usually a potentiometer, is connected to the indicator drive wheel which also drives a belt that positions a pointer with respect to a scale. The pointer and scale provide the set point indication. When the pointer hits a pointer stop, or for any other reason resists motion, further rotation of the thumbwheel causes the idler wheel to move to engage a mechanical stop to prevent further thumb pressure from causing dislocation between the indicated set point value and the set point value source.

摘要： A periodically oscillating electro-optical scanning apparatus for indicating the position of registration lines or edges relative to itself and, when desired, to provide servo control of either the material bearing the lines or edges relative to the apparatus or the apparatus relative to the line or edge. The optical scanner is positioned relative to the material containing the indicia to eliminate output signal deficiencies. The output signal of the scanner sensing head is phase demodulated to obtain a tracking error current. This error current is combined with the oscillation reference frequency to effect displacement of the scanned area.

摘要： A synchronous motor is provided which includes a platen and a head disposed in displaced relationship to the platen for movement along a single axis or a pair of coordinate axes relative to the platen. The synchronous motor may operate on the basis of variable linear reluctance. Pickoff means may be disposed on the head to measure the displacement of the head relative to the platen along the single axis or the pair of coordinate axes. The signals from the pickoff means are introduced to actuator means on the head to obtain continued displacements of the head relative to the platen along the single axis or the pair of coordinate axes. Signals may also be introduced to the actuator means to represent force signals for producing a controlled acceleration of the head relative to the platen along the single axis or the pair of coordinate axes. In another embodiment, signals representing desired displacement along the single axis or the pair of coordinate axes are combined with signals representing actual displacement of the head relative to the platen along these axes to produce error signals for use in a closed loop servo to drive the head to the desired displacements. Servo means are also provided for preventing rotation of the head about the coordinate axes.
