  • Patent number: 8612065
    Abstract: A position encoder provides one or more trigger outputs based on position signals developed within the encoder, in addition to traditional position output signals used by other system components such as a motion controller. The trigger outputs may be used directly by a triggered device, bypassing the motion controller and obviating any separate trigger generation electronics. The trigger output(s) can be fully synchronous with the encoder's position output signal(s) with essentially no latency or jitter, increasing accuracy and providing improved system performance. The trigger functionality can be incorporated in a variety of encoder types (e.g., absolute and incremental) and technologies (optical, magnetic, inductive etc.), and used in conjunction with different position output signal formats (e.g., quadrature, serial).

    Abstract: A motion controller is provided which improves system responsiveness without having to raise the arithmetic capacity of a master controller or to boost the communication speed of a network. The master controller 1 uses a program analysis unit 1g to separate, from a control program designating a tolerable delay time for operating control target apparatuses, a slave use program to be executed by a slave controller in a manner not to exceed the tolerable delay time, and to create slave-to-slave communication setting information needed by the slave controller to execute the slave use program. Through slave-to-slave communication, the slave controller 2 acquires input/output information from another slave controller. The slave controller 2 also uses a slave use program execution unit 2f to execute its own slave use program.

  • Patent number: 8452425
    Abstract: A position control device for suppressing occurrence of stick-slip during a feed operation performed in a very low speed region is provided. Adders add an output obtained by multiplying actual speed deviation by a proportional gain, an integral component of actual speed deviation obtained by inputting actual speed deviation to an integral compensator, an output obtained by multiplying motor speed deviation by a proportional gain, and an integral component of the motor speed deviation obtained by inputting motor speed deviation to an integral compensator. The result is output as a torque feedback command. Each integral compensator has a coefficient changer capable of changing a coefficient from 0 to 1 to adjust integral gains in accordance with a speed feedforward command or a speed command. Large integral gain increases the response speed of switching from static to kinetic friction torque in a very low speed region thereby suppressing occurrence of stick-slip.

  • Patent number: 8452424
    Abstract: In a case where a position command path for a control position of a load 5 that is equivalent to a moving object is set by issuing a position command Rc(z), a gain for one of a high-frequency component, a specified frequency, and a specified frequency width is constrained. This means that a resonant frequency can be constrained, and that after the position command Rc(z) arrives at a target position, a position detection signal Y(z) can also arrive at the target position in a set number of steps. It is therefore possible to perform positioning at high speed and with high precision by constraining a resonance mode of a mechanism that includes the moving object, and a feed-forward control can be performed that meets target positioning times that are set for various types of operating patterns.

  • Patent number: 8195368
    Abstract: The present invention is typically embodied to exert active control of two same-shipboard cranes performing joint lifting of a payload. Sensory signals indicative of ship motion, and of luff angle and hoist line length of both cranes, are transmitted to a computer. The sensory signals are processed by the computer using a ship motion cancellation algorithm, which solves for values of the respective luff angles and hoist line lengths of both cranes, such values achieving static equilibrium (e.g., zero motion horizontally, vertically, and rotationally in the same vertical geometric plane) of the suspended payload. Inverse kinematic control signals in accordance with the mathematical (e.g., minimum norm) solutions are transmitted by the computer to respective luff angle actuators and hoist line length actuators of both cranes so that the suspended payload tends toward steadiness. Inventive control thus acts on a continual basis to significantly reduce pendulation during the two-crane lifting operation.

  • Patent number: 8146481
    Abstract: An actuator in which overshooting has been reduced is provided. A cylinder is divided by a piston to provide first and second chambers, and first and second control valves 41, 43, which adjust fluid pressure supply to respective chambers in a non-step manner, and first and second discharge valves 42, 44, which control outflow of fluid from the first and second chambers, are provided. A first control device carries out feedback control of pressure to be supplied to the first or second chamber such that a difference between a target position of the piston and a detected position of the piston becomes smaller. A second control device carries out differential-preceding PD control to bias pressure to be commonly supplied to the first and second chambers such that the difference between the target position of the piston and the detected position of the piston becomes smaller.

  • Patent number: 8131385
    Abstract: A positioning device includes a driver which moves a positioning object and a sensor which measures the distance to the positioning object in a non-contacting manner and outputs a detection signal if the positioning object is detected only in a length measuring area within a predetermined range from any detection position, shaft controller which stops the driver by detecting the detection signal from the sensor and automatically correcting for an overshoot amount between the stop position and any detection position, when the driver moves the positioning object and the sensor, and the positioning controller that stores the coordinate value after the automatic correction by the shaft controller and that performs the positioning based on the reference coordinate value.

  • Patent number: 8055360
    Abstract: A system and method of aligning a stent with a stent support involves taking two images of the stent that has been placed on the stent support and determining from the two images whether the stent is aligned with the stent support. The stent can be rotated so that the two images are of different views of the stent. A computer can be configured to receive the images and to determine the whether the stent is aligned. A backlight can be used to take images of the stent in silhouette. A portion of the stent support can be re-positioned based on an image taken of the stent.

  • Patent number: 8032238
    Abstract: A mechanical system selectively imparts a prescribed motion to an output load using two or more actuators, including at least one having an active material element. The output load can be a locking member when the system is a vehicle transmission, a shuttle car of a linear system, or another device. A controller determines a total motive force required for imparting the prescribed motion, and selectively commands a combination of the actuators to provide the total motive force, apportioning the total motive force between the various actuators to optimize the performance of the system. An algorithm determines which combination of the actuators is the most suitable in moving the output load, and continuously modified this combination as needed as the output load is moved. The other actuator or actuators are then selectively energized as needed to provide the total motive force depending on this suitability determination.

    Abstract: The present invention provides techniques for splitting bundled inputs and outputs into separated Boolean inputs and outputs for function blocks of automation devices. More specifically, previously-defined bundled inputs and outputs may be used, whereas separated Boolean inputs and outputs may be used as well. In other words, the newly added Boolean inputs and outputs do not replace, but rather compliment, the previously defined bundled inputs and outputs.
