计算力矩—自校正机器人控制算法

近年来已经开发出一些应用于复杂非线性系统的自适应控制方案,机器人控制系统就是典型的例子。由于不可避免地存在着非模型化的动特性,将自适应技术和基于模型的非线性控制有机地结合起来,充分利用能够得到的参数模型,通过自适应控制处理剩余的未知参数部分,可能是一种有效的控制策略。本文提出一种适用于机器人的计算力矩—自校正控制算法。仿真结果证实了方案的有效性。

THE AIGORITHM OF COMPUTED TORQUE -SELF TUNING CONTROL FOR ROBOT

Some control schemes for complex nonlinear systems have been developed recently and the robotic adaptive control is one of the typical examples. Due to the inevitable presence of unmodeled dynamics,if the adaptive control technique combined with nonlinear model-based control takes full advantages over any known parametric model while dealing with the remaining unknown parameters by using adaptive control,it may be an efficient control strategy, therefore.an algorithm of computed torque-self tuning control for robot is presented, whose simulation results have proved its effectiveness.
