which file implements the husky_velocity_controller?

When I controll the husky simulator, the motion of husky is driven by the /husky_velocity_controller/cmd_vel, I send a cmd_vel topic as expected velocity, the robot moves. But from physics, we know there must be a controller that transform the cmd_vel signal into the force that drives the vehicle. Where can I find the implementation of this controller? in which file? Thanks.

The source for that is in the ros_controllers package, here:

Specifically, if you want to see how it handles the cmd_vel topic it records the command and does the logic here:

isn't it just a choice of which to pass through?
