  Hello

  I'll expand a bit what Angela said on the. ENDS and then try to clear up the pins.

  The SPICE model that you use for the PA78 includes several subcircuits and models. Best practices for creating a component in Multisim are having one. SUBCKT or. MODEL for each component. The point of this is to ensure that the additional models or models contained so that they do not interfere with each other in the final netlist. The best way to solve this problem is to move the. ENDS during the main subcircuit until the end of the complete draft - so, instead of simply add the. ENDS at the end, you must also remove the first. END of line in the file. For this circuit, you probably don't need to do it, however in general, it's a good idea to do by making a component like this.

  With respect to the pins, step 6 of the component wizard asking you order the pins will be used in the model. The (original) model that you have only 10 knots, so it isn't a problem if you have only 10 pins there. If you have 12 pins on your symbol, and only 10 model nodes, then you score just two unused pins as "NC"(vous pouvez également ajouter deux broches"fausses"pour le.) ". SUBCKT which is what you did, but you have not).

  For the rest of the pins, see the. SUBCKT line and comments just ahead of him:

  * PINOUT ORDER +IN -IN IL OUT +VS -VS CR+ CC+ CR- CC-* PINOUT ORDER  7   6   1  2   12  4   8   11  10  3.SUBCKT PA78 7 6 1 2 12 4 8 11 10 3
  

  Comments indicating the order of broaching tell you the order in which the terminals must be indicated when you use the PA78. SUBCKT. As you can see on the. Line SUBCKT and comments, even if IT is pin 1 on the component, it should actually be listed third when you use the. SUBCKT. It's asking you to step 6 in the component wizard. Step 6 allows you to specify the order in which to use the pins to Multisim. The comment you indicates that + is the model node 1, - IN is model node 2, IT is the model node 3, etc., and then you say Multisim by setting the number of nodes of model

  

  Hope that helps!

• Control and simulation and data acquisition

  Hello

  I am applying to motor control in Labview. I'm sampling speed from DC engine in real time through an acquisition of data. (my sampling time is 1000 samples per second)

  Then wrap speed as input to a Simulation (simulation and design of the order) and inside the loop simulation, I have a PID controller. The PID has the actual speed of the engine for the acquisition of data and the engine reference speed as input.

  Reference engine speed comes from the generator of signals (control design and simulation-Simulation) and is a waveform.

  My step in the engine size is 1000.

  I am running this application real-time and drawing the reference signal and the motor real signals. I run into several problems with regard to the calendar.

  1. when I change the size of the step of the simulation loop, the frequency of squares of reference also seems to change. For example. What step size = 1000, duration of pulse = 1 s. What step size = 100, pulse width = 0.1. (My pulse frequency is 1 Hz, Simulation clock - 10 kHz). How step size can affect the pulse width.

  2. can you explain the relationship between the DAQ, the Simulation step size loop sampling time, Loop Simulation period.

  3. If I want to collect different sets of data using sampling different hours, it's OK to change the sampling DAQ time without changing the size of the step of the simulation.

  Would also like to emphasize that the DAQmx calendar under sample clock mode is placed in front of the simulation loop and the output is connected to the loop simulation.

  Appreciate any help.

  Hello

  Maybe some screenshots of your code would help. Furthermore, what you have read your samples together with your DAQ screws?

  (1) If you have a waveform, the output is specified as:

  

  For example, if you change the size of the step of the simulation loop, you change the simulation time which are introduced into the signal generator and affecting the waveform that you see if you do not have a size quite small step to characterize the waveform that you generate.

  (2) sampling DAQ rate is the speed at which samples are taken on the acquisition of card data itself. The size of the simulation step, help. "Specifies the interval between the time when the ODE Solver evaluates the model and updates the results of the model, in a few seconds." Simulation loop, still using, "Indicates the amount of time that elapses between two subsequent iterations of the loop of control & Simulation.". " "Step size determine the value of t that is introduced to the functions you use in the loop simulation while the loop simulation period controls simply to how fast you change the following t value. The sampling rate of DAQ hardware is a clock of completely separate hardware controlling the analogue-digital on the DAQ card converter so that you can get a deterministic dt between the samples being acquired.

  (3) you can change the schedule for the acquisition of data, but you will need to restart each time the changes take effect. If you change the calendar of data acquisition and want your values to correlate with your simulation, you will need to change your size of step as well.

• External template function (control and Simulation Module) on Linux using target

  Hello

  I am trying to run the 'EMI_Integrator.vi' for example on one OR cRIO-9024 (nor a myRIO).

  I moved the file 'EMI_Integrator.so' to the ' / or-rt/system ' on the cRIO and the .so file added to the target in the LabVIEW project. I can not navigate to the .so file directly so I specified the .so path manually, but the VI is not able to run and an error of-2366 'reissue model '.

  "You can find the original version of VI in the Finder for example OR", but I've included my modified version that has a LabVIEW project and targets already loading.

  Thank you

  Mitch

  Hello Mitch,

  If you want to use the external model on a 9024 node, you must copy the appropriate VxWorks library (.out) file to the/or-rt/system folder of the target. The .out file is located in LabVIEW\Examples\Control and Simulation\Simulation\External model Interface\EMI_Integrator\RT-Lib\vxworks.

  In LabVIEW, have the external model node refer to the file of the library appropriate for your operating system. In my case, I use a .dll for Windows file located in the folder EMI_Integrator, above.

  When I run the VI on the cRIO target, referring to the library on my host computer, it will automatically search the folder to/or-rt/system for a file with the same name with .out.

  Kind regards

• System ID: estimated incompatibility of response and simulation

  I use the VI express Estimation of transfer function SO to model a system plant transfer function. The actual data are a step response, where the stimulus is a flow rate report, and the answer is the size of the droplets resulting (it is a system of generation of Fluid emulsion, decreases of drop size as pump ratio increases).

  My problem is when I compare the response data simulated that I see in the "preview" when configuring the express VI, a plot of the simulated response using the model TR Simulation.VI - they do not match, the form of the response is quite different. I'm relatively new to the design and the system id modules command, so I guess I'm doing something wrong.

  A screenshot of the vi express overview as well as Panel frontal/block is attached, as well as the file data and vi.

  TIA

  After puzzling on this for two days, I finally understood the error on mine, obviously only a few hours after I posted this question! (I should have posted earlier )

  For the sake of posterity.

  error #1: I use the data in a table, and I forgot the model IF Simulation.vi wire in the sampling rate
   
  error #2: the transfer functions did not correspond to the preview of express VI and on my front panel because I had not specified the type of realization in convert it IF transfer Function.vi - default value is 'minimum' and it was therefore minimizing States. Change in full sets this inconsistency.

• Qosmio G30(Japanese model) and television in Australia,

  Hello
  I bought a Qosmio g30 Japan about 6 years ago. I have now returned to Australia and want to watch TV on the qosmio. The cables provided to the Japan do not fit the connection of the antenna into the wall in Australia. I guess that I'm not the only person who has a Japanese model and wants to use it in Australia. Nobody knows what kind of converter plugs that I need?

  Any help is good.

  Pat.

  Hmm maybe you can order this adapter to a Toshiba ASP in your country
  Otherwise, you will need to check some special electronic merchants in downtown, perhaps they could provide an extra adapter for antenna cable

  Good luck

  N ° when running on a PC of the class, you are working with a set of standard material (with its clock 1 kHz) and a non-deterministic BONE, and there is nothing you can do about it. That is why acquisition cards NOR are all smart devices with their own processors, memory, and clocks.

• Space required on target RT for LabVIEW Control design and Simulation

  Hello

  I want to run a DLL file on an RT target using LabVIEW Control design and Simulation, but I'm not sure of the required amount of RAM on the RT-target. My RT-target options are respectively cRIO 9002 and cRIO-9004 with 32 and 64 MB of RAM. Is this a sufficient amount of RAM to run the simulation? ¨¨

  Thanks in advance

  This will depend on the size of your dll, the size of the rest of the code, you can create other necessary drivers/modules, memory use when your application runs, etc.

  9002 and 9004 have not a lot of RAM on them and the minimum software installation to run a control application Design & Simulation (CD & Sim) will take around 22Mo of it (the majority of RAM available to the 9002). It would be possible to run your application on these two controllers if you keep it small but it will depend on what you want to do.
