摘要： A motor translator with an up/down counter which inputs a preprogrammed read-only memory for selectively driving a multiple phase stepping motor. The read-only memory stores data at preselected locations and generates drive signals in a sequence which corresponds to the coil switching sequence of the stepping motor. The drive signals generated by the read-only memory in response to direction signals received from the up/down counter are applied to the motor for selective energization thereof.

摘要： A motion control system includes a single stage gear reducer and power screw, a brushless variable-speed electric motor with position and velocity sensing instrumentation, a solid state power amplifier, and a programmable controller. During operation an absolute positional reference is established when the slide actuates a non-contacting limit switch to signal that the slide is within less than one motor revolution of the correct starting point. A memory accessible by a microprocessor has paired values of velocity and position stored in a table representing ideal such values for deceleration portions of the motion cycle. Alternatively, the microprocessor computes each new value of position and velocity in real time as required to update the velocity commands sent to a comparator. The comparator compares the predetermined slide position to the actual slide position and signals the microprocessor that a change in output to the motor power supply is required. A digital to analog converter converts the motor velocity signal that issues from the microprocessor to a variable d.c. voltage whose magnitude varies over a range that determines the sense of direction and speed of the drive motor.

摘要： A servo system, particularly well suited for use in a computerized numerical control system for a large machine tool, in which a plurality of axis controlling servo circuits are controlled by one computerized axis controller. As each controlled axis moves, an attached resolver's output is digitized to generate a digital position feedback signal which is compared to the desired position in the computer. The resultant error signal is converted to an analog voltage to control said axis motion. A digital clock and counter drives two digital to analog converters to create the two resolver inputs, and supplies timing signals to the computer, thus synchronizing the system.

摘要： An adaptive closed-loop controller is described that reduces repetitive speed variations of precision rotatable mechanical components, such as rollers, casting wheels, pulleys, gears, pull rollers, extruders, gear pumps, and the like. A system is illustrated in which the controller is coupled to a motor for driving a rotatable mechanical component in response to a motor control signal. A sensor is mounted to the shaft of the mechanical component, and generates a speed signal representing angular velocity of a mechanical component. The controller receives the speed signal, and generates a set of data elements to relate speed variations of the mechanical component to a plurality of angular positions of the mechanical component over one or more revolutions. The controller generates an error signal based on the data elements and introduces the error signal into closed-loop control circuitry to provide adaptive control over the mechanical component.

摘要： Where a rotating device, for example, such as a lathe, a pen-recorder, etc., is used to depict a non-circular shape, a position of a cutting tool, a pen, etc. is controlled by a method such as NC (numerical control). Generally, delay in control occurs due to the transmission characteristic of the control system, thus producing a distortion in the formed shape. This distortion can be removed by inserting an element having a reverse transmission characteristic into the control system.

摘要： The disclosure describes a digital servo control circuit to actuate an analog servo motor smoothly from an actual present position to a new desired servo position in response to digital information from a computer. The control circuit described receives from a computer digital information representative of a new position desired at a predetermined velocity rate. Such information normally is pre-timed to correspond with a preselected timing rate in the digital computer. A position signal generator is responsive to such pre-timed digital information to generate a predetermined number of position signals intermediate of the pre-timed digital information to achieve the desired smooth operation of the servo motor.

摘要： Apparatus is disclosed for controlling the movement of a movable element between an initial starting position and a final stopping position. The apparatus comprises drive means coupled to the movable element and responsive to motor drive signals for moving the movable element along a predefined path between said starting and stopping positions; and first generating means for generating a first command velocity signal having a first state when the actual velocity of the movable element exceeds a predetermined value and a second state when the actual velocity of the movable element is less than the predetermined value. A controller periodically senses the state of the first command velocity signal when the movable element has less than a first predetermined distance and greater than a second predetermined distance to travel to the final stopping position, and controls the levels of the motor drive signals to cause (a) the acceleration of the movable element by the drive means when the first command velocity signal is sensed at its first state, and (b) the deceleration of the movable element by the drive means when the first command velocity signal is sensed at its second state.

摘要： A digital computer is programmed to control the acceleration and deceleration of a stepping motor. A buffer is utilized to indicate the number of times the motor is to be stepped during a specified movement of the motor. A table is utilized to indicate selected periods of time between steps of the motor in order to achieve a selected rate of change of the motor''s velocity. The number of the means for indicating, which number is indicative of the number of times the motor remains to be stepped, and the addressed location of the table are updated each time the motor is stepped. Repeated steps of the motor are made after waiting a period of time corresponding to the table location addressed. The motor accelerates, decelerates or rotates at a constant speed depending on the change or lack of change of the table location used.
