this was not a negative review, however, I just wanted to compare it caught my eye, the difference in speed compared to the speed output of our various engines.
Although the settings are important and the result must be adjusted to suit everyone
Wasn't taken as negative
just to try and make clear that the biggest difference is in the fast motions like bumps, a wiper motor will need more time to reach it's target in these movements.
e.g. a wiper of 60 rpm with a 5cm arm theoretically travels from top to bottom in 0.5s so as long as this speed isn't asked by the game there is no problem.
but with bumps sometimes it requires "instant" movement.
Here's a theoretical sample, this does not represent the actual curve of a sim, but it should explain the difference:
The grey line represents the wanted position, the red line the actual motor movement.
• If a motor is too slow it will never reacht it's destination because it's direction gets inverted before it's in position
• If a motor is only just fast enough it will reach it's destination but delayed
• If a motor is fast it will reacht it's destination close to the desired point
The problem with fast motors is that we have to "tame" them so they won't move too fast/harsh on subtle movement and won't overshoot, that's where PID (which is still sort of abracadabra to me as well) comes in.
Hope this sheds some light on the subject.
