Can someone help me out?
Why does my acceleration signal look like this? Why isn't it a smooth line?
Is it somewhere in the setting? Did i chose a wrong solver?
The signal is from a transform sensor from Simscape.
MATLAB: Does the acceleration signal from simscape looks so weird

In the "Simulink-PS" block that converts the motion input to a physical signal, under the Input Handling tab, make sure that the signal derivatives are not set to “Zero (piecewise constant)”. By changing this entry to, e.g., "Filter input, derivatives calculated", and selecting a filtering method with a reasonable time-constant, the velocity signal appears as expected..
Another reason why the measured velocity is zero could be because the motion input signal to the joint is very "aggressive" and numerical calculation of its derivative (which is also dependent on the time step) might not be accurate. In this case, appropriate tuning of the solver step should resolve the issue.
Hi,
Note that the cross-product block is actually doing 
x ω, which is equal to 
x 
.
x ω, which is equal to x .Thanks,
