Abstract In this paper, a direct iteration method is presented for two-time scale decomposition of flexible structures. This direct eigenspace approach has less computation burden than the eigenvector approach. It is also a canonical transformation to keep the equation symmetry and has also explicit inverse so that the input and output matrices of decoupled model with the same sensor and actor as the original system can be easily obtained.

[abstFig src='/00290003/02.jpg' width='300' text='Underactuated rimless wheel model for collisionless walking' ] In this paper, control methods for achieving collisionless walking of robotic underactuated walkers are discussed. Collisionless walking is a gait type of motion that does not cause collision during the landing of the swing-leg end. First, we introduce a simple point-footed walker and develop its motion equation. Second, we propose two time-scale output deadbeat control approaches and demonstrate mathematically their ability to generate a stable, collisionless walking gait. Overcoming potential barriers at midstance as well as the stability of zero dynamics are guaranteed accordingly. Furthermore, we investigate fundamental gait properties through numerical simulations.
