Motor backlash - modeling in simulink?

[truongpm]

Hey,

I am trying to understand the effects of motor backlash and how to possibly model it in Matlab/simulink. The system I am trying to model is a servo turning an active rocket thruster (think vernier thruster for attitude control). What would be the best tool for this issue in simulink?

You can do it precisely how it is done in this video

With an added DOF consisting of a spring dashpot.
