Combining suppression of the disturbance and reactive stepping for recovering balance |
Abstract | ||
|---|---|---|
This paper proposes a new framework to recover balance against external forces by combining disturbance suppression and reactive stepping. In the view point of the feedback control, a reactive step can help to diminish the disturbance caused by an external force that should be compensated to maintain balance. In other words, if the adequate step is performed, the feedback controller does not have to compensate all of the external force by itself. Under this concept, we propose an original solution to distribute the compensation between a feedback controller and a reactive step, according to the period of support phase and a disturbance characteristic. We first clearly distinguish between the role of the disturbance suppression and the reactive stepping. Then, based on this distinction, the small disturbance of external force or happening late during the single-support phase, is mainly suppressed by state feedback. The large disturbance which is out of capability by feedback controller and at the beginning of the single-support phase, is absorbed by modifying reactively the next steps. The proposed method is validated through experimental results with the HRP-2 humanoid robot. |
