中文摘要 |
提出一种基于最优化线性搜索的方法规划人形机器人的步态. 通过对脚踝关节末端轨迹运动的规划和参考零力矩点(ZMP: zero moment point)轨迹的规划, 将最优化泛函极值问题转换成为基于非线性约束最优化的问题,将连续空间多变量规划问题转换成为离散空间二维变量规划问题, 提出了一套能够在线规划步态的控制算法. 该算法的收敛性和稳定性在仿真和实物上都得到了验证. |
英文摘要 |
Linear search optimal algorithm is used in the humanoid biped robot’s gait planning. By planning the trajectory of both of the ankle and the zero moment point(ZMP), the functional extreme optimization problem and the continuous multi-dimension variable programming problem are respectively converted into a nonlinear optimization with nonlinear constraints, and a discrete two-dimension variable programming problem. An on-line gait planning is then proposed. Astringency and stability are also verified on both simulation and physical robot. |
