Is there a simple VI for PI control of DC motor using labVIEW?

[Valentino Rossi]

I am trying to control DC motor position using PI algorithm. I have succeeded in achieving using proportional control, but I need to fine tune it using PI control. I am using one analog input channel which gives the DC motor's current position, and counter output whose frequency and duty cycle control the DC motor. I am working with PXI6251 card. Can you help me with a VI for PI control?

Why don't yuu use the NI labVIEW PID control toolkit?

I am not able to open the link. Do I have to pay for the toolkit?

This is the correct link.

This toolkit comes as part of NI Developer Suite. Also you can buy this toolkit separately.

If you can't spend the money on the PID toolkit then you will need to spin your own. Information and links can be found in this post. You can also take a look at the Simple PID Demo. Can't really say anything about this example as I've never used it. I simply did a search (amazing tool these days).
