针对多关节机械臂轨迹跟踪控制,提出了一种全局快速终端模糊滑模控制方法。该方法根据滑模控制原理,采用模糊控制调节滑模控制的切换增益,并利用积分的方法自动对系统的建模误差和干扰的上界进行评估,实现了对建模误差和干扰的自动跟踪,削弱了抖振。文中利用李亚普诺夫定理证明了系统的稳定性,仿真结果表明了其有效性。
Aiming at multi-joint manipulator trajectory tracking control, a global fast terminal fuzzy sliding mode control method is proposed. According to the principle of sliding mode control, this method uses the fuzzy control to adjust the switching gain of sliding mode control, and uses the integral method to automatically evaluate the upper bound of modeling error and interference of the system, and achieves the automatic tracking of modeling error and interference , Weakening chattering. In this paper, the system stability is proved by Lyapunov theorem. The simulation results show its effectiveness.
