Hi again,

thanks for the explanation. Since your last post i have read some theory of PID Controllers and can now fully understand whats happening. Ok now the details of my Robot. I built a functional model of Top Spin (http://www.capte.org/img/enciclopedia/TopSpin.jpg).
I want to to let it run like in real. The Arm is very heavy about 1kg and its driven by both EV3 Motors with a transmission of 2100 degrees per round. I connected the EV3 to a AC/DC Adapter. If i use the built in Ramp Up it will start too slow in the first third and then accelerate too fast in the last third of the ramp, it looks really unnatural.
In the last third of the ramp i have also the problem that the load is too much for the motors and its speed of accelaration at this time.
