Abstract

The multi-degree-of-freedom robot is affected by the abrupt change of environment and disturbance of its own components

which leads to instability of control. In order to improve the stability of the multi-degree-of-freedom robot

a closed-loop control method of multi-degree-of-freedom robot based on error feedback fusion tracking is proposed. A parameter identification model for inertial tracking of a multi-degree-of-freedom robot is established

flexible control of drive mechanism components of the multi-degree-of-freedom robot is carried out by combining a multi-factor constraint parameter fusion method

an adaptive control law for inertial error feedback of the robot is established

a mechanical parameter optimization analysis model and a dynamic model of the robot are established

parameter adaptive optimization in the closed-loop control process of the multi-degree-of-freedom robot is carried out by combining an error feedback adaptive correction method and an inertial compensation method

and the robot position and posture adaptive adjustment is carried out according to the parameter optimization result

so that the stability control of the robot is realized. The simulation results show that the control error of the multi-degree-of-freedom robot using this method is small

the control stability and robustness are strong

and it can quickly converge to a stable state.
