Any PID experts ?

Thanks everyone

- We currently are using an anti-backdrive motor but may not be in the competition. Without the anti-backdrive, the motor may have to be powered somewhat to hold position and we are wondering if we could overheat it.

- yes, good idea, if we could design something where the effects of gravity can be neutralized (gigantic spring), I could see how the current PID class could work well but so far we don't know how to do it. So currently with the same power, going up goes slowly and controllable, going down races at high speed and gathers lots of momentum. This behaviour is a bottle neck to a super high performance (ie high speed) ladder.
