In this paper,UR robot's motion control and singular perturbation algorithm are studied in depth.First,paper analyses mechanical structure of the UR robot;secondly,the inverse kinematics of UR robot are solved through numerical iteration method,and verify the correctness and speed of algorithm based on strictly control the accuracy and speed of the algorithm.Then,a control method is proposed based on singular perturbation,the system is divided into two fast and slow subsystems to achieve reduction effect through the vibration suppression method.Finally,the manipulator trajectory curve is drawn to base on forward and inverse kinematics algorithm,and system controller reduction order.Experimental results verify the effectiveness and accuracy of the proposed algorithm.
