def brake::sim_actuator::Test::cmd	(	self,
		dx
	)

Command actuator to do relative move.

@param dx = encoder ticks to move.
@returns time (in seconds) required to get there.

This calculation assumes a triangular velocity profile with
constant acceleration |a|, applied first in one direction,
then in the other.

Erase any previous plan, then move the actuator in two steps:

  (1) accelerate in direction requested;
  (2) decelerate to zero velocity

The real device supports a trapezoidal velocity profile with a
maximum velocity (vMax).  Since it takes a long time to reach
vMax, this model ignores that detail, which does not seem to
matter much in practice.
