  • Numerical Techniques for Optimization of Gait Generation

    Carnier Rodrigo Matos, Fujimoto Yasutaka

    IEEJ JOURNAL OF INDUSTRY APPLICATIONS ( 一般社団法人 電気学会 )  10 ( 2 )   236 - 246   2021.03  [Refereed]

    Joint Work

    　View Summary

    <p> Optimization of robotic bipedal walking widely uses simplified dynamical models to minimize the computational cost and generate fast solutions, but this poses the problem of modeling errors and increased inaccuracy. Moreover, direct methods of optimization are almost always used; however, most are not implemented to satisfy Pontryagin's Principle, which can lead to suboptimal solutions. This study presents the optimization of planar robotic bipedal walking using exact dynamics. We apply pseudospectral optimal control to optimize gait generation using two accuracy requirements: nonlinear multi-degree-of-freedom whole-body dynamics and satisfied conditions of optimality according to Pontryagin's Principle. In order to consistently achieve solvability of optimization in this type of problem, we present a novel methodology consisting of synergic techniques that address well-known numerical difficulties of optimization.</p>

  • Precise External Force Estimation of Helical Motors using Magnetic-attractive-force Error Compensation

    Koyama Masato, Fujimoto Yasutaka

    IEEJ JOURNAL OF INDUSTRY APPLICATIONS ( 一般社団法人 電気学会 )  10 ( 2 )   178 - 183   2021.03  [Refereed]

    Joint Work

    　View Summary

    <p>This paper presents the external force estimation for helical motors contain the magnetic levitation system. The helical shape of helical motors induces a wide inductive gap; thus, their thrust density is 1.5 times higher than that of general cylindrical linear motors. Furthermore, by magnetically levitating the mover, the motor can be directly driven. However, owing to the variations in the magnetic attractive force acting on the mover, the accuracy of external force estimation is lower than that of cylindrical motors. To solve this problem, this study proposed the combination of the thrust and torque disturbance observers of this motor for external force estimation irrespective of the magnetic attractive force. Numerical simulations and experimental results demonstrated that the proposed method can achieve the highest precision.</p>
