Set the rate of acceleration

What you want is a rate limit on your joystick command.

You want the LabVIEW equivalent of something like this:

o = joystick;
if  (o > op+d) o = op+d;
else if (o < op-d) o = op-d;
op = o;

... where

"joystick" is the present value of the joystick command
"o" is the output to the motor controller
"op" is the previous output to the motor controller
"d" is the maximum change you want to allow each iteration
