Description
The block Backlash allows the representation of a system presenting a mechanical play like system of gearings. When the input increases (decreases), changes of the input of the block Backlash give equal changes of its output. When the input changes direction, the system is disengaged during a short moment (the play is called deadband or gap). Therefor, at the initial moment of the change, the input has no effect and the output remains constant. Then, changes of the input give equal changes on the output up to the next change of direction of the input.
Parameters
