• 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.

• Live PID missing under Header Control Design and Simulation

  Hello

  I have currently the full version of the University of Labview 2009, but the PID screws are missing. I understand that they are under Control Design and Simulation, but there is nothing in this topic.   In addition, an image of my license manager OR is attached to show which is enabled.  Any ideas?

  Thank you

• There is no tools in the control design and simulation its Blanck

  There are no tools in control design and simulation its Blanck. I saw the same question asked before and found a solution that, if we install 32-bit labview then all options will be available. I installed labview of 32 bits, but the result is the same. Please help me thanks in advance...

  So yes, I think that it is possible to use this tool as a trial.

  but you have to install after installing LabVIEW.

• Control Design and Simulation Tutorial

  Hello

  I begin with a course that requires the use of the Control Design and Simulation functions. Before asking stupid questions, I want to see the hand on the tutorial, it is referenced in this white paper.

• control design and simulation in a loop the final amount not what I expected

  Hi the LabVIEW forum members.

  I have a frame control and Simulation in which I am simulating a regulator in closed loop (see file attachment).  When I apply a step of the input unit that I expected to get the answer to deposit at the unit, i.e. the stage of entry being the set point.  However, he moved to about 0.625.

  Can someone point me in the right direction please?  I'm obviously doing something wrong here.

  Kind regards

  OK guys,

  Cancel my last post, I found my mistake, it was the P + I control shape, I made a mistake in the Integral control action transfer function where the Integrator not arrive to integrate an error.

  Kind regards

• How to make my waveform in the simulation design and control work continuously?

  Hi all, I m a begineer to Labview and have a few question.

  I use the Labview to design and implement a controller for FOPTD system, but I found that the waveform in the 'loop control and simulation"does not work continuously. I mean keep repeating in the same graph from 0 to 10 seconds. Is there an approach to make it run continuously?

  Thank you very much.

  Whenever a loop Control Design and Simulation is executed, it connects a full simulation, the initial time for the last time. When you drop a new loop CD & Sim down, the default values are zero second initial time and 10 seconds for the last time. I guess what you probably want is for simulation do not stop at 10 seconds. Double-click the left node attached to the CD & Sim loop and extend the end time. You can change the end of 'Inf' time if you want it to run until the VI is stopped.

• Closing state space control loop

  Hello

  I am a student MYSELF and has been assigned to a project closing a loop of a rotary inverted pendulum control.

  I have all the mathematical equations and state space design.

  I don't have any idea on how to apply the system in closed loop state space in Labview (10)

  any suggestion where start/examples?

  Thank you very much

  Gil,

  Hello Gil,.

  A great way to implement and simulate your SS system is to use the Module LabVIEW Control Design and Simulation.

  Here is a short list of references on modeling in LabVIEW

  Basics of Control Design and Simulation in LabVIEW
  http://zone.NI.com/DevZone/CDA/tut/p/ID/10685

  Tutorials for LabVIEW controls

  http://zone.NI.com/DevZone/CDA/tut/p/ID/6368

  Once you have installed module, it is an example of navigation in LabVIEW on the inverted pendulum.

  I hope this 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.

• Representation of State-space Discrete in FPGA

  Hi all

  My goal is to simulate a State-space model is the FPGA cRIO (order to use an observer).

  I am currently trying the simulate on my computer without using the VI state space discrete Control Design and Simulation Toolbox (since there is no model of State-space for the FPGA VI). However my representation of the discrete state-space model does not work.

  It is under a continuous state space model:

  

  Then I got the model discretized (using the zero-order-hold and t = 0.01 s):

  

  Here are the State-space discretized model I designed (to develop a similar model in the FPGA):

  

  This is the VI space of discrete states that I use to compare the results:

  

  The chart plot the State X 1, which is growing indefinitely. However, it should look like a first order, as you can see:

  

  I don't understand why the State X 1 progresses like this, I know I'm missing something (saturation of integration?).

  Thanks in advance

  Kind regards!

  PS: Does anyone know if application other than the PID controller is feasible in the FPGA cRIO? I also have to wonder about the inversion of the matrix if I want to use the Kalman gain in my observer.

  PS2: I apologize for my disorganized/not clear Labview files, I start with him.

  Hello

  I think that the problem can be caused by errors in your matrices A and B of rounding.  Have you tried to make her show values more accurately?

  MATLAB calculates these values as: A = [0.995, 0.009925; 0 0.99], B = [2.488e - 5; 0.004975]

• Discreet Integrator (control and Simulation Module) - LabVIEW 2015

  Hey everybody,

  I'm trying to drag the discreet Integrator on a block in 2015 of LabVIEW diagram. All other vi in the "range of discrete linear systems are draggable, but not the"discreet"Integrator." I noticed the same thing for the continuous Linear Systems Integrator. Anyone explain how to solve this problem?

  Sincerely,

  Lex

  Lexicondi,

  Unfortunately, these functions cannot be moved out of the loop control & Simulation. We support only discrete transfer, of State spaces and ZPK models function.

  So, if you want the "discreet Integrator" outside of the SIM card, you have the following options:

  one) to use the "discreet transfer function" as T /(z-1) (or any other type of discretization available in discreet Design continuous monitoring);

  (b) you can develop your functions inside the control and the Simulation loop and then create a subsystem of her. The subsystem can move outside the SIM card also. Here, you can use any SIM function you want;

  I hope that this should be sufficient for your application.

• control and simulation Module spring mass

  I'm using Labview 2010, and tasked the simulation module (just 15 days before the date of expiry. trying to see if the program will work before I spend $4 K) and try to calculate the dynamic response of a spring index.

  I was able to complete the program in the simulation section (I think). I now need to feed a sign of acceleration in the module which I have already captured at a sampling rate of 100 k/s.

  Test technician said I should add 500 ms from zero to the front of the track to make sure that the system is stable before the trace of acceteration of power is in the simulation module. I have alreay done reading and adding zeros to the chain.

  I can't feed the trace in the module control and simulation.

  The engineer said he was able to do the math in MatLab and simulink (I think), because I have not used this program and we do not have a copy I am doing it in LabView.

  In addition, I would add that this forum is blocked by my firewall to work.

  If you need more information, I'll have to return to work and get it.
