• feedback loop on the impact force

  Hello

  I use labview 8.5 and a card Ni USB-6221 to control the power output of an actuator and monitor the output signal of a load cell.  The actuator allows strength 50 Hz which is measured by the sensor.

  The signal from the load cell is basically a very narrow peak occurring at a 50 Hz.  I want to measure the height of each peak, average figure (maximum strength varies from 2 or 3%) and then use this data to provide a feedback loop to keep the constant force applied.

  [img] http://farm4.static.flickr.com/3067/3077344302_4b7bb5f2a3.jpg [line]

  I tried to use 'amplitude and levels' vi 'peak', for an average to exit mode.  However, this seems to give a result fluctuate widly which is useless for feedback purposes. I tried to increase the sample of this vi period with no luck.

  Anyopne there any suggestions on how to do this? I could do this using the detection of peaks of waveform?

  Any help or advice would be greatly appreciated.

  Thank you very much.

  Hi John,.

  Thanks for your post and I hope that your well.

  To create a circular buffer in LabVIEW, you can use a shift register. However, for large number of data points with a large displacement to register on the side of the loop are stupid and impractical. This is why you must use a table, in which you update the value of the old with the new value, and you set the size of the table for the number of points you want to have in the buffer.

  I have created an example of a buffer in LabVIEW 8.5 - Please see attached VI.

  Also, if you do any static anylsis so perhaps consider using the functions of point by point, which no longer require the updated value to calculate the most recent average (for example). This saves because of the calculation table in its entirety every time.

  Hope this helps,

• Save 1 array in a loop for the other run cycles.

  I have a function built into a N = 65 for the loop that pulls down real-time data in table.    On the first loop, a table for "calibration" is created that needs to be saved as a reference for measures in the next 64 executions.

  Anyone know what I need to do to save this first set of data, so I can continue to use it?   On the next run, the function extracts completely new data and replaces naturally.

  For the moment, I don't have a source VI to post (that works), sorry about that.   Will try get ot something tomorrow... but it will probably not work.

  To be a little more exactly...

  

• If doesn't work is not inside the loop for the registration of the declaration file?

  Hello!

  I have the following documents open in Photoshop:

  123456_mrp_ou. TIF

  869548_mrp_ou. TIF

  896589_mrp_in. TIF

  896589_mrp_ou. TIF

  .. and I have this if statement in a loop for to search for files with a specific 'pid' number and save them in the folder My Documents:

  var originalPid = 896589
  for(i = 0; i < app.documents.length ; i ++) {
        activeDocument = app.documents[i]
          if(activeDocument.name.substring(0,6) === originalPid) {
                  var standardSave = new File('/Users/constantincerdan/Documents/' + activeDocument.name)
                  activeDocument.saveAs(standardSave, TiffSaveOptions, false, Extension.LOWERCASE)
  }
  }
  
  
  

  It did not find the two files and save them when I run. However, the loop without if statement runs very well and saves all the documents in the Documents folder:

  var originalPid = 896589
  for(i = 0; i < app.documents.length ; i ++) {
        activeDocument = app.documents[i]
                  var standardSave = new File('/Users/constantincerdan/Documents/' + activeDocument.name)
                  activeDocument.saveAs(standardSave, TiffSaveOptions, false, Extension.LOWERCASE)
  }
  
  
  

  How it works with an if statement so that it saves only the two?

  Any help is very appreciated!

  You are comparing apples to oranges, you need to compare strings.

  originalPid = 896589;

  alert (typeof originalPid);

• effective solution for the algorithm

  I have that table t defined below.
  
  1. definition of t table.

  with t as 
  (select 'A' CODE from dual
  union all
  select 'A' CODE from dual
  union all
  select 'B' from dual)
  select * from t;

  (1) in the plsql code, I have to return the cursor ("o_cur") on table t, I can achieve:
  Open the o_cur for
  Select * from t;
  
  (2) as varivale 'i_code' is given and an output variable 'o_code' must be returned with the following logic:
  
  If o_cur has on file "i_code" value then return o_code = i_code,
  Otherwise, if o_cur has exactly on the line then return o_code value as value in this one folder.
  otherwise return o_code = null;
  
  What is the way of effecients to achieve step 2?
  
  I can do of the Nations United-effectively these 2 questions:
  
  count (1) select 2.1)
  in t v_count;
  
  count (1) select 2.2)
  in t v_count
  where CODE = i_code;
  
  And then writes the logic step "2") to get the value of o_code variable to output. But it seems slow.
  
  Maybe I can query cursor already opened "o_cur" somehow? Or is there a better way?
  ---
  
  I can only do this way:
  

  with t as 
  (select 'A' CODE from dual
  union all
  select 'A' CODE from dual
  union all
  select 'B' from dual)
  select count(1) CNT
  , max((case when t.CODE = 'A' then 'Y' else 'N' end)) YN 
  from t ;--rowcount=3, 'A' in list
  
  
  with t as 
  (select 'A' CODE from dual
  union all
  select 'A' CODE from dual
  union all
  select 'B' from dual)
  select count(1) CNT
  , max((case when t.CODE = 'C' then 'Y' else 'N' end)) YN 
  from t ;--rowcount=3, 'A' is not in list

  That seems the best solution.

  THX,

  I can add additional column in the cursor to output, which have same value on all lines indicating the number of all records. So if I add this additional column in the cursor output "o_cur" so I can go get a line from him, close the cursor and opens again. And FRO mfetching a folder I get information on the total number of records. But as you can see algorithm I nEtape '2') also requires the knowledge of the weather, the input value "i_code" appeared in the cursor result set.
  I think I do better additional query after openeing the cursor as:

  with t as
  (select 'A' CODE from dual
  union all
  select 'A' CODE from dual
  union all
  select 'B' from dual)
  select count(1) CNT
  , max((case when t.CODE = 'C' then 'Y' else 'N' end)) YN
  from t ;--rowcount=3, 'C' is not in list
  

  Another analytic function can be used to test for the existence of a value in the result set, for example

  Here I used the sum function to sum up the number of jobs CLERK in the results. This indicates a '1' for all of the lines stating there the value 1 CLERKS in the result, even if it has not yet been selected by the cursor.

  Himanshu salvation,

  To start reading your matrix of the second line, you can use a table of Index function once you have loaded the table of your spreadsheet file. The function Array Index lie in the range of functions under functions > programming > Board Index. The help of LabView is very useful to explain how to use this function.

  With regard to the accuracy of the numbers when read you the spreadsheet file that you read is formatted in fractional chain, since form you it converted into a mixed string before saving. In order to recover all the precision, read the worksheet as a string and then convert it to a string using a string Fract/Exp to fractional numbers conversion function. This feature is on the range of functions for String > String/Number Conversion > Fract/Exp string in number. The help of LabView is also very useful for explaining the operation of this function.

  Best,

• Improved speed for the LabVIEW MathScript calculation

  I use a MathScript node to perform calculations on a sbRIO FPGA module and the speed of these calculations is critical.  What are some ways to improve the speed of calculations and y at - it a faster way to make calculations of MathScript matrix?  If I belong the MathScript in a Subvi it will improve the speed of calculations?

  Thanks for any ideas

  Please look at the VI attached. She is your original code ".m", my changes to your ".m" and G code equivalent to the updated code ".m". First, let me describe the numbers that I've seen on a cRIO 9012 for each of the three approaches.

  I ran to each of the three approaches for the hundreds of iterations, ignored the first 30 iterations to allow allocations of memory (which caused a huge spike in runtime performance about the RT), then took the average operation time for each iteration of the loop for the remaining iterations

  Original M: 485 msec/iteration

  Updated M: 276 MS/iteration

  G: ms 166/iteration

  The changes I made to your code ".m" are:

  (1) added; at the end of each line to remove output (used for debugging)

  (2) left random code generation - used whitenoise (seems like that is what you did)

  (3) turn on the type of data highlighting the function. Noticed that the majority of data was cast in the complex, although that did not seem like you need the complex domain. The source has been function sqrt. Changed using real (sqrt (...))

  This improvement in performance by more than 40%. I believe that more can be pressed if you follow the documentation - MathScript wrote for real-time Applications.

  Then I took the MathScript you and equivalent written G leaving the algorithm as it is. This gave us the improvement of the performance of another 40 per cent in the G. updated the it is a known issue that on slow controllers, MathScript adds a penalty of 2 x to g equivalent. We are investigating this issue and may be able to fix it in a future release.

  If you are profiling the G code, you will notice that most of the time we spend in the multiplication of matrices. Unless rethink you your algorithm, I doubt that this can further improve.

  Let me know if you have any questions

• back to zero 'loop' for Interior "Subvi.

  Hi guys,.

  Silly question perhaps extreme but fast. I have a fairly large VI with several of the Subvi. Inside of these sub - VI, there are some for loops that do not seem to whenever the Subvi is called. While making the analysis of the data, it basically accumulates the data of the previous file as well. For example:

  folder a. gives 4 results of loop for the Subvi

  file B gives 5 results of loop for the Subvi

  Not appear in the final as having 9-results and not the 5 that I expect.

  I've been playing with deletion of points of interest, but I was wondering if there was an easier option?

  Initialize works the cordoning off of the node as a first call, and since it is always in memory it is reset only once.
