| 摘 要： | 针对高能耗导致的两足机器人实用化障碍,提出了一种全新的、系统化的步态能效优化控制方法.基于两足机器人运动的重要能耗指标(平均功率、平均功率偏差、平均力矩损耗),提出了能耗预估策略和能效优化算法,获取了零力矩点(ZMP)稳定区域内的能耗极小值.沿着能耗极小值所对应的上体轨迹对机器人步态实施能效优化控制,最终获得满足ZMP稳定判据的低能耗步态.仿真结果证明,该方法能够有效降低机器人能耗并保持其稳定性.

| Abstract: | A gait control based on energy-efficiency optimization is proposed for solving the fatal problem of high energy consumption in practical application of biped robots. A strategy of energy consumption estimation(ECE) and an algorithm of energy-efficiency optimization are proposed based on three important indices of energy consumption for biped locomotion average mechanical power, mean power derivation and mean torque consumption. Controlling the gait of the robot along the trunk trajectory which corresponds to the minimal energy consumption in the zero moment point(ZMP) stability domain, we obtain the energy-efficiency gait guaranteeing the ZMP criterion. Simulation results show the validity of the method. |
