Nonlinear Analysis and Discrete Learning Position Control for a Multifingered Hand
-
摘要: 本文通過分析機器人多指手爪的靜摩擦、庫倫摩擦、粘性摩擦等非線性因素,推導出多指手爪屈伸關節的動態控制模型;針對多指手爪的非線性影響,提出了一種位置離散學習控制方法,并給出了這種方法的收斂性定理.仿真結果表明,離散學習控制方法能在有限次迭代后使手指關節位置達到期望位置.Abstract: Based on nonlinear factors analysis of static friction,Coulomb friction,viscous friction etc.for a multifingered robot hand,the dynamic control model of a flexion-extension joint is derivied.To overcome the nonlinear effects,the discrete learning control strategy is presented.The convergence theorem is also given.The simulation result shows that it can make finger joint position reach desired position after finite times iteration.
