Web1 mei 1999 · The minimum commanded torque change model, which is proposed here as a computable version of the minimum motor command change model, reproduced actual trajectories best for curvature, position, velocity, acceleration, and torque. WebThe last part of the trajectory has generated a change of sign (concavity) that permits to fit into the exit shape. This event provoked a minimum value of the curvature under −0.08[m−1 ], which could end up in a tight turn. These final values will be re-adapted in the following iterations of the real-time trajectory planner. C.
