Error in Mathscript (FOPDT Transfer Function)

[YukiWong]

Thankyou very much barp,

Although the solution can show non-minimum phase behavious,but because i want to monitor the parameter (rise time, overshoot) of the system in the front panel, i can't use control and simulation loop and connect to "CD Parametric Time" as it will produce an error. Do control and simulation loop incorporate any function block to monitor the parameter?

Again thankyou very much ya barp 🙂

yes, you are correct. We don't have a function to directly measure those properties. However, the beauty of LabVIEW is that you can code 'around' it....

If you open the "CD Parametric Time", you will find the functions to measure the properties you need. You just need to provide with the right arrays. But using resampling to convert from the XY value to the necessary array and by using those functions, you can measure those properties from a step response. Here is the code:

Okay, thanks barp, its work now, u really help me a lot 🙂 thank you very much, appreciate it
