Problem regarding bode plot of higher order system

[tanu87]

I want bode plot of very higher order system in labview. But it always shows the error "Analysis:  Input parameters has at least one element that is Inf, NaN, DBL_MAX, or DBL_MIN".

Give me some solution of it.

Hi tanu,

well, the solution to that error message would be to filter out those "wrong" input parameters...

[tanu87]

How could I filter out those input. I have 592 order system.If give some example it will be helpful.

[tanu87]

It shows "Error -20068 occurred at NI_LinSys_LinSys Conversion.lvlib:CD Convert TF to ZPK (LinSys).vi".

Hi tanu,

You have to provide an example, which illustrates the problem you want to solve!

Sorry, about which signature? I have already given my example, where the error occurred. So give the solution kindly.
