Re: PID Inputs and Outputs

Quote:
I am wondering if the inputs into the PID SubVI need to be scaled in order to match the input.
I meant output there

I did make the setpoint and the process variable the same scale by having the second Encoder Get wired to the shift register, but the main concern is whether it is a problem having the PID control a speed based on an error in angle.

My process value and outputs are angle so they can by as high as 90 degrees or more. Its the output range that I've limited to -1 to 1 in order to match motor speed.
