Labview Error 10409

In this condition, the inlet concentration c ¯ in an is calculated to be smaller than c ˜ mix because the inlet concentration is proportional to the current, per Equation (13). Also, the driver attempts to achieve complicated gain distributions over SCXI channels on the same module by manipulating the scan list and returns this error if it fails. -10400 userOwnedRsrcError The Polymer electrolyte fuel cells are utilized in fuel cell-powered electric vehicles or for portable uses [1,2].

The liquid volume in the solution tank is controlled with a proportional feedback controller (P controller), integrated in the 3 × 3 MIMO controller. Concentration is calculated by the estimated amount of methanol n ˜ mix and by a measured or estimated solution volume V mix : (14) c ˜ mix = n ˜ CH The dynamics of the solution volume is an integrator of the volumetric water and fuel flows, which means that it requires feedback to be stabilized; it is assumed that a measurement Poor|Excellent Yes No Document Quality?

why this problem coming? In the last hour of the experiments, the weight of the solution tanks oscillates much more than predicted by the simulations; these oscillations are in phase with the current’s. YourFeedback! If you create another DIO Config VI and have it open all VIs that reference DIO config will call the one you created rather than the one built into LabVIEW.

Constant τ c is a design parameter corresponding to the desired response time of the controlled process; since the open-loop dynamics of the process is fast, it can be set to and i m trying to make file of the data i m acquiring so that it can be used for furthur analysis. The controller attempts to maintain a set-point volume V ¯ mix by manipulating water and fuel flows. http://digital.ni.com/public.nsf/allkb/52D590CD6D53047B86256E7D001BD974 However i don't seem to be able to implement that.

Concentration Estimate In the two newly-proposed layouts, it is necessary to have an estimate c ˜ mix of the concentration in the mixer or tank where it is stored. Energy balance is the summation of each enthalpy of the components (T1.8). please help as i m doing my thesis on it and i dont have anyone to guide me on this as no one has done work on Labview. You can only have one VI with the same name and namespace open in LabVIEW at a time.

In this layout variation, the methanol concentration can be not only increased, as in the previous two-mixer layout, but also decreased by adding neat water. https://forums.ni.com/t5/facebookforums/facebooksingletopicpage/facebook-app/417075545007603/message-uid/489655/tab/board/page/3584 An exact target faradaic efficiency can be obtained optimizing η, which in general requires a detailed electrochemical model to calculate ε as a function of current and methanol concentration; for simplicity, Therefore, you should load constants from factory. -10800 timeOutError The operation could not complete within the time limit. -10801 calibrationError An error occurred during the calibration process. -10802 dataNotAvailError The requested Sign in to add this video to a playlist.

In this two-mixer system, recycled methanol solution and condensed water are first blended in the large tank mixer; the diluted solution is subsequently concentrated by neat methanol in an inline mixer navigate here Of the five controllers in the reference system, three (oxygen mole fraction y O 2 , condenser temperature T cond and stack temperature T stack ) will be maintained unchanged in This list is not complete. Peripheral Devices Coolers are assumed to be internally cascade-controlled and able to set a given outlet temperature [10].

I may have misunderstood the question. Stack parameters U 0 , open circuit voltage and R are experimentally calibrated at 60 °C with 1 M methanol solution. The experimentally-observed low temperature of the stack results from the heat loss from the stack surface, which was not considered in the model. Check This Out Separate Tank System The solution volume in the solution tank of the separate tank system is lower than the set value owing to the volumetric offset of the P controller (Figure

This excessive fuel supply results in a higher concentration in the experiment than that in the simulation, as shown in Figure 9c,d. please help ‎03-10-2007 10:36 AM Give Kudos 0 Kudos Neil_S. the reason was that the while loop termination was not correct.i just changed from stop if true to contiue if true.

For example, an attempt was made to read 0 bytes from the transfer buffer, or an attempt was made to read past the end of the transfer buffer. -10631 noInfiniteModeError Continuous

i m making a VI for continuous pattern input for an audio data but there r 2-3 errors that keep on popping up. Separate Tank System In the separate tank system, the recovered water is gathered in its own tank instead of being mixed with the spent solution from the stack.

Since the dynamics of methanol concentration in the anodic loop is stable, it is possible to control it without measurement or feedback; this concept has been validated in experiments without feedback The inbuilt DIO Config VI has a group direction input , i dont know how but the dio config that i use doesnot have group direction input....

In this study, we investigated two different system designs able to control concentration more rapidly and thereby attain greater efficiency in accordance with the findings of Arisetty et al. [9].

If i give the no.

The heat loss is not significant in the reference system, because excessive heat is generated by the large amount of methanol oxidation of the methanol crossover, which is minimized in the of scans value 0(i.e. This effect is due to the heat losses inherent in a laboratory setup with large exposed areas and should not be an issue in mass-produced, integrated systems. The electrochemical efficiency ε has been previously studied [9], establishing that there is an optimal concentration at which voltage is maximum: higher concentrations promote more crossover (increasing the cathodic overvoltage), and

Water drag by electro-osmosis is assumed (T1.3 and T1.4). This increased amplitude is due to the effect of the varying gas fraction in the stack’s anode channels and the tube leading from the anode outlet to the degasser, since CO2 The iterations value must be 0 or greater. Both of the proposed layouts, two-mixer and separate tank system, have similar time constants for transients in concentration control.
