When using driveline I can easily output the position and velocity of a mass with an ideal translational motion sensor:
However, to get the acceleration of the mass, I need to convert to simulink and differentiate the signal. This is not a major problem but my questions are as follows:
How can I be confident I am not introducing error by numerically differentiating?
Why doesn't the "Ideal Motion Sensor" supply the acceleration as an output? I would think the equations of motion include acceleration and it is integrated to get velocity and position.
Thanks in advance,

Hi Peter
This is good feedback, maybe there should that option in the sensor. But this can be solved by adding that into a modified component (Simscape language) with acceleration output. Let me know if u need a hand.
Cheers Juan

Hi Peter,
Find attached the implemntation of the sensor in a test model.
We have a 1-day course on Simscape where you can learn how to create your own components/domains. See link below:
