Active control of vibration of the flexible mono-faisceau

Hi, im working on the active control of vibration of the unique flexible built-in beam, and I need to design that helps me control the beam active & passive.

two experiences of control a robot with unique flexible bond. The link is operated in bending by two piezoelectric glued to the surface, and the local curvature is measured by piezoelectric sensors, forming a pair of sensors/actuators colocated. In both experiments, the articulation describes the same polynomial trajectory that excites the Eigen modes of vibration of the binding. In the first experiment anti-vibration with piezoelectric actuators are off, and we can observe a very long time to maneuver as link oscillations themselves naturally. In the second experiment anti-vibration are lit, and a significant reduction in the time settling is reached

Cabo,

So, it looks like part of what you are trying to do is the generation control system a PID in LabVIEW. Fortunately, LabVIEW includes a number of useful resources for the PID:

Here is one of our books (with the tutorial files) whites, discussing implementations in LabVIEW PID: http://www.ni.com/white-paper/6440/en/

Here is another tutorial on implementing PID using the PID.vi: http://www.ni.com/pdf/labview/us/implement-a-pid-control-system.pdf

Here is the help documentation for PID.vi himself: http://zone.ni.com/reference/en-XX/help/371361L-01/lvpid/pid_vi/

Finally, example finder LabVIEW has a large number of projects example PID you can experiment with. Just go to help > find examples, then find "PID" and select any project matches your planned the best implementation.

  • Active control is indicated

    When running my application, the active control in the UI has a black outline that I find unattractive.  Is there a way to make disappear?

    Thank you.

    As much as I know there is no way to disable the highlighting in the active control. However, if the command has a lable, the highest point is around the lable instead of the control itself, it also means that if you move the lable off area of the visible screen (for example with a value of 5000 left label) the nail will not appear on the Panel.

  • Abnormal activity - a volume control bar appears in the upper-left

    I installed Windows 8 PRO (64-bit), on my Dell laptop (model Inspiron-5520) 05/11/2012.
    For the last 15 days or more, I'm observing some abnormal activity which I do not know if it is due to a virus, malware or some drivers / registry corruption.
    Whenever I open a Windows session (e.g. after reboot or out of the MODE STANDBY), a volume control bar appears in the upper-left corner & it keeps inhibition - reactivate up until I got a hit. This volume control bar is similar to that seen after that now both pressed keys (Fn & Speaker-Mute).
    I took the question to Kaspersky Antivirus, but still it is not fixed. I scanned the whole system of Rescue CD (bootable) of Kaspersky and Avira antivirus also scanned the whole system using Microsoft msert.exe service. But this virus as activity does not stop.
    I have observed that if the WINDOWS AUDIO service is stopped through msconfig, this virus as activity stops. But then speakers & microphone stop working.
    After crossing research on various Web sites on the internet, I found a site that helped me to fix the registry of the Windows Audio service. And it has worked very well; but it lasted only 2-3 reboots. Then after that, it is indeed.

    Can you please do the necessary to let me know if it is really a virus / malware or not. And the solution to get over.

    Hello

    Volume control you see is normal Win 8...

    He does the things you describe are not...

    I doubt it's apparent virus but... it's very probably an audio driver\program any that is defective...

    Look in the tab Services from msconfig and hide all Microsoft Services and see what remains...

    You can also view the Startup tab of the the Task Manager for a suspect...

    It could be something as simple as a pilot action which was only supposed to run once, but loads with boot every time by a malfunctioning...

  • How to make a ComboBox that make the active control on the page?

    I have a ComboBox and a button on my page.  I managed to make the default command button. However, I need the comboBox control to the active witness, which means, when the page is finished rendering, the cursor is inside the ComboBox text entry, so I can start typing.  I don't want to have to click in the part of text, and then start typing?

    Note: I tried. setFocus(), who control 'focus', but the cursor does not blink inside the comboBox, I need to click inside the text input for the area of text to "relive" and let me start to tap into it.

    Note: The comboBox control is parented by a Panel.

    Is this a problem of starting time?  Browsers do not activate the Flash Player until you click anywhere in the SWF file.  There is a way to deal with this in IE, but not all browsers

    In general, you get the best results using the Zoom feature. Proportionally, this increases the text and images on a page and minimizes the weird glitches.

    Original title: user account with an effort of parental control

    After logging in to my admin account, I created two user accounts for my children, set up parental controls for both that I created, when I tried to set up the third account that he would allow me to activate parental control. It seems that he is trying to load the screen to give me the parental control options then the window disappers and another small window appears saying "cannot make changes to parental controls settings. If the problem persists, see your system administrator. I close the window, and then open the parental controls for other accounts, and they work very well, allows me the chance to change. I deleted the third account several times, making sure to create on behalf of others, just like I did the first two. Still no luck. Can I have only 3 total accounts? My administrator account and standard users 2.

    How can I get a standard user account third with parental controls?

    Hello

    Create a new user account and check if the problem persists, the problem does not persist in the new user account, then fix the damaged user account.

  • Why timelines in Active AND inactive what is the purpose?

    Insert a button box or click on and the object appears in the panel mounting with an icon pause in the middle. On the left, the subject is active and inactive right.

    What is the possible purpose of adding something that is not active?

    The object can be modified to be active for the duration of the timeline required - in order to drag the object in the timeline as needed and no need to add a little more for inactivity (useless)

    Am I missing something here?  Can I do a button - then inactive - active assets then again along the timeline?

    Yes I am new but this logic fails me, unless there is some use or better yet, it can be changed to ' all the assets "when placed

    A click box is by default invisible to the user, never inactive a period as you say. The suspension with a click box, always at the end of his timeline, which means she is always active for its entire duration.

    A button, a button of form (and a text entry area) are visible to the user. In the default configuration, they stop to 1.5secs regardless of the duration of their chronology. Before the point of interruption, they are active. What happens when the button is clicked, is defined in its success (or as the last attempt for a valid BER) action. If you decide that the head of continuous play, the shape of the button/box/TEB will not disappear, but they will be inactive. As long as you do not release the playhead with this action, the user can use the object again.

    You can change the time of the break in the distribution panel, or by dragging the thin vertical line on the timeline. I'm perfectly happy with the current situation, because I have total control over what is happening. The limit is that you can have a single asset and inactive a period, because there is only one suspension point possible.

    You want to add this link if you want to learn more about the timeline. I should update (when I have time) because Captivate 9 effects timelines are integrated within the timeline of the slide.

  • I have two Apple TV. The remote control that interferes with the other. For example, if I press stop on the distance she also those other programs. How to do this?

    I have two Apple TV. The action on each distance affects the other tv. For example if I press stop on the remote control will stop the program on the other tv to. How can I stop this from happening?

    Easy.  You must associate each ATV with one of the remotes.  Each ATV is not paired and will 'listen' to any distance.

    The trick is to cover before the other ATV when matching so the two do not listen.

    Silver or white remote control: pair or cancel the twinning of the Apple Remote with Apple TV (3rd generation or earlier)-Apple Support

    Siri remote control: http://help.apple.com/appletv/#/atvbc9953e63

    Don't know what models you have the ATV, but the whole process is the same:

    1. choose a remote control and an ATV.  Cover the front of the another ATV.

    2. hold the remote control in 3 inch they recommend, pair it with appropriate above process.

    3. choose the other remote, unlock the first ATV and block that you just paired.

    4. hold the second remote control 3 inches from the second ATV and pair it with appropriate above process.

    5. release the first ATV and enjoy.
