| Outline of Final Research Achievements |
In order to drive the electric vehicles using motors (automobiles, trains, automatic guided vehicles, etc.) efficiently, the energy loss should be minimized during its operation. In this study, a design methodology of the optimal trajectories of torque, rotating speed and so on to minimize the energy loss when the operation time, rotating speed, and rotational angle are given as drive conditions. However, the optimal trajectory may cause sudden acceleration and deceleration. Hence, trajectories are designed to be smooth in order to suppress the jerk and slip phenomenon between wheels and road surfaces.
The effectiveness of the proposed method are illustrated by means of experiments and simulations.
