Hi all Be quick mates, i am in real trouble with time closing down and i really need your help. Any idea reply fast!!! THanx Ashmex

Hi dhuff i am quite newbie to labview, could you just illustrate how to enter a transfer function (2s+10/2s2+.014+100)in a vi and post the vi in this forum or mail it to me at ashmex2005@yahoo.com Thanx

Hi all i need to input a second order transfer function in my vi and the available tranfer function blocks are in frequency domain while im working in time domain. Plz if you know how to do it as it's done in simulink or in a similar block diagram notation, help me out. thanx Ashmex

Hi all I need to design a process control vi of a fermentation plant, my problem is that, i am finding it difficult to customize tanks, draw pumps and valves and assign transfer functions to the objects. if you know how to it or you know about any site which allows download of vi's, do reply the links to my message. Also, if you have any such vi, plz do mail it to me. Thanx Regars Ashmex

hi all plz have a look at the attachments.. Thanx a lot for your replies Download File:post-1634-1109960583.vi Download File:post-1634-1109960585.doc

Hi all i need to input a first order differential equation in an equation node. My problem is that, while integrating the output signal with an integratore express vi,i am feeding back a dynamic type signal to another input of the equation node. the initial input is a floating point number, which is leading to an error. Plz help me out of it. Plz find the vi attached. Thanks a lot

Hi all I need to model a process governed by a difference equation: yk = 250Uk + 25Uk-1 -2.65 yk-1 + 400 Which has yk as current output, yk-1 previous output and Uk as the current control signal and Uk-1 previous input . Plz help me implement this equation using shift registers, equation node or any other possible method. Thanx a lot? Regards Ashmex

Hi all i am quite newbie to labview and i need to input a first order differential equation in an equation node. My problem is that, i am feeding back a signal to an input of the equation node which is of integer type while the initial input is a floating point number, this is leading to an error. Plz help me out of it. Also any vi concerning process control, would be most welcome. i am finding it difficult to draw standard items like pumps, valves... any hints how to customize these items. thanx
