    摘要:

    针对多机械臂力/位混合控制受摩擦力等不确定因素影响的问题,该文提出了一种基于模糊自适应鲁棒滑模算法的控制方法。首先,根据机械臂及物体的动力学方程,构建多机械臂系统模型,并将模糊算法与自适应滑模算法相结合;然后,对不确定因素及未知非线性项进行补偿,利用鲁棒算法对系统可靠性进行提升;最后,基于李雅普诺夫方法,证明了该系统的稳定性。仿真结果显示,该方法可显著提升控制器的控制精度和系统响应速度。

    Abstract:

    Subject to the friction and other uncertain factors, the multi-manipulator force & position hybrid controlling method is still a challenging issue. To investigate this problem, this paper proposes a hybrid control method based on fuzzy adaptive robust sliding mode algorithm. Firstly, the multi-manipulator system model is constructed with consideration of both multi-manipulator and the object dynamics equations. Secondly, the fuzzy algorithm is combined with the adaptive sliding mode algorithm to compensate for uncertain factors and unknown nonlinear terms, so as to improve the system reliability. Simulation results showed that, both controlling accuracy and responding time of the system can be improved by the proposed method.
