| Abstract(in English) | Possible functional roles of the phase resetting control during rhythmic movements have attracted much attention. The phase resetting control is a control mechanism, in which the phase shift of periodic movement is induced depending on the timing of a given perturbation, leading to the dynamical stability. The phase response curve (PRC) is known to quantitatively evaluate the phase shift in the phase resetting control. It is found that an optimal PRC for bipedal walking becomes bimodal. From a mathematical point of view, we consider how such characteristics can be obtained. First, we assumed a nonlinear oscillator and a phase excitable element as a model of Central Pattern Generator for controlling rhythmic movements. Second, we constructed feedback control systems by combining them with joint actuators. Next, we numerically computed PRCs of such systems and compared their dynamics and resulting PRCs. We further derived analytical solutions of the PRCs approximately and investigated them systematically. From the results, we clarify the occurring conditions of the bimodal PRCs. Here we show the relationship between the conventional analysis based on perturbation methods and our analysis, and consider the extensibility of our approach. In fact, we expand our approach to apply it from one degree-of-freedom systems to multiple degrees-of-freedom systems, such as walking robots and robot arms. Finally, we discuss the optimal design of phase resetting control mechanism bipedal walking. |
