Recently, 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 dynamical stability, such as a rapid transition from an unstable state to a stable state in rhythmic movement. The phase response curve (PRC) is known to quantitatively evaluate the phase shift in the phase resetting control. It has been demonstrated that an optimal PRC for bipedal walking becomes bimodal, and the PRCs acquired by simulated reinforcement learning are qualitatively consistent with measured results obtained from experiments. In this study, we consider how such characteristics are obtained from a mathematical point of view. First, we assumed a symmetric Bohoffer-Van der Pol oscillator and a phase excitable element known as an active rotator 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 the resulting PRCs. Furthermore, we calculated analytical solutions of the PRCs approximately. Based on the results, we investigated the parameter dependence of the analytical PRCs systematically. Finally, we will discuss requirements for realizing an optimal PRC for rhythmic movements. |
