Detailed Description
Edge defining the cost function for limiting the translational and rotational acceleration at the end of the trajectory.
The edge depends on three vertices 
, an initial velocity defined by setGoalVelocity() and minimizes:
![$ \min \textrm{penaltyInterval}( [a, omegadot ]^T ) \cdot weight $](form_3.png)
.
a is calculated using the difference quotient (twice) and the position parts of the poses
omegadot is calculated using the difference quotient of the yaw angles followed by a normalization to [-pi, pi].
weight can be set using setInformation()
penaltyInterval denotes the penalty function, see penaltyBoundToInterval()
The dimension of the error / cost vector is 2: the first component represents the translational acceleration and the second one the rotational acceleration.
- Remarks
- Do not forget to call setTebConfig()
- Refer to EdgeAccelerationStart() for defining boundary (initial) values at the end of the trajectory
