摘要

针对仿人机器人步行过程中存在的机器人关节角加速度约束影响控制性能的问题，提出一种考虑关节角加速度约束的仿人机器人偏摆力矩控制方法.该方法充分考虑了双臂在摆动过程中对偏摆力矩的影响，根据力矩平衡条件得到需要抵消的偏摆力矩的大小与方向，将偏摆力矩的控制问题转化为带约束条件的二次规划问题，并设计了一种在线变步长迭代算法计算得到优化后的双臂摆动轨迹.实验表明，该方法能有效抵消机器人步行中产生的偏摆力矩，避免控制过程中的削峰现象，有效提高机器人的步行稳定性.

Abstract

To cancel the effect on control performance due to joint acceleration constraints during humanoid robot walks

a new yaw moment control approach with consideration of joint acceleration constraints is proposed.After analyzing the effect on stability caused by the motion of arms swing

the undesired yaw moment which needs to be counteracted is computed.Then

the yaw moment control problem is formulated as a quadratic programming problem with inequality constraints.To solve this optimization problem effectively

an online variable step-size iteration method is designed to generate the trajectories of arms swinging.The experiment and simulation results verified that the proposed approach can effectively compensate yaw moment

avoid peak cut-off phenomenon and guarantee the stable walking.
