| Outline of Final Research Achievements |
In this work, we have investigated control theory for nonlinear systems, especially for underactuated systems. The goal is to design control schemes to achieve dynamic motion which cannot be yielded by simple stabilization techniques. The achievement of desired motion with small energy consumption is also the goal of this work. We have first considered three kinds of characteristic motion of underactuated systems: (1) quick motion generated by unstabilized motion, (2) motion with small energy consumption, and (3) motion effectively utilizing the gravity effect. Then, we have dealt with actual mechanical systems for these kinds of motion and proposed control laws based on the investigation of the motion characteristics. Moreover, we have given convergence/performance analysis and demonstrated the validity of the present schemes via numerical simulations and experiments.
