摘要

提出了一种基于线性倒立摆模型动力学的双足机器人平衡控制方法。通过设置质心、俘获点和零力矩点作为LIPM的状态,利用线性系统的状态反馈对它们进行同步控制。考虑到机器人控制系统是数字化的,分析和控制器设计都是基于离散系统。仿真结果验证了该方法的有效性。并在WALKER机器人站立式推恢复实验中对其进行了评价。

Standing Push Recovery Based on LIPM Dynamics Control for Biped Humanoid Robot
This paper presents a control method based on LIPM (Linear Inverted Pendulum Model) dynamics for the balance control of biped robot. By setting CoM (Center of Mass), CP (Capture Point), and ZMP (Zero-Moment Point) as the state of LIPM, we use state feedback of linear system to control all of them synchronously. Considering that the robot control system is digital, analysis and controller design are based on discrete system. Simulation results verify the effectiveness of the proposed method. It is also evaluated in the experiments of the robot WALKER standing push recovery.
