I need a PID control routine in labview, does anyone have one that works?
I have the PID toolkit, and have tried implementing there sub VI's but they just flat out don't work. Mostly because they are SLOW AS MOLASSES.
Here is what i want to do. I have a shaker, and an LVDT on the shaker.
The shakers input is power, not displacement. So i need to control the displacement of the shaker by using feedback from the lvdt as the error signal. I will be using a complex displacement waveform which i have represented as a displacement table in excel.
So in essence, i prescribe the displacement, the pid controller outpus some "power" out and adjusts that power signal to closely follow the displacement table?
How would i go about doing this? Im using MX.
