Thank you for being condescending without any elaboration.

When you combine a PID control solution with a real device, there are many situations that result it stabilizing at a point that is not the setpoint. To elaborate, if you were using only P to attempt to get to a setpoint when lifting an object, the system would most likely stabilize below the setpoint. The small power generated when near but not at the setpoint in this case would likely be too little lift the load the last bit.

Also, one of the main purposes of this forum is to help people with problems. That wasn't condescension, it was being helpful.
