Abstract

A new approach for robust motion control of critical joints in humanoid robots is presented in this paper. Structural stiffness, frictions and delays induced by the communication network will be fast and properly compensated with an algebraic model-free control algorithm. Moreover, robustness to parameter variations will be analyzed and compared with an advanced PID-based control law. Simulations will show that not only good tracking quality can be obtained with this novel technique, but also that it provides a very robust behavior to the system.

仿人机器人柔性关节的鲁棒运动控制
提出了一种新的仿人机器人关键关节鲁棒运动控制方法。由通信网络引起的结构刚度、摩擦和延迟将通过代数无模型控制算法得到快速和适当的补偿。此外,还将分析该控制律对参数变化的鲁棒性,并与一种先进的基于pid的控制律进行比较。仿真结果表明,该方法不仅可以获得良好的跟踪质量,而且对系统具有很强的鲁棒性。
