Re: PID I value tuning issues

Unfortunately, Kd is also dependent the proportional gain. LabVIEW uses Kp, Ti, and Td.

However, this does not mean you need to throw PID rules of thumb out the window. Generally, I find an oscillating Kp like you did, add Td until I achieve a step response that fully dampens after 1-2 small overshoots (or less depending on the application), and then add in Ti if necessary to reduce steady-state error.

Hope this helps
