摘要
Abstract
Currently, the humanoid robots instead of human beings performs a significant function in the fields of industry, mine safety etc. To decrease security risks caused by the robots running away owing to the misoperations, the stability control technologies for robots should be further improved. So this paper proposes a global finite-time tracking controller based on the nonsingular terminal sliding mode control, which could solve trajectory tracking control problems of humanoid robot system under uncertain disturbance. Firstly, the dynamic model of humanoid robot with 5connecting rods was built through La-grangian method, and then the sliding model controller for trajectory tracking was designed based on nonsingular terminal sliding mode. Secondly, the sign function was replaced by the modified saturation function in the controller for eliminating the chattering problem caused by non-continuity. Finally, the simulation results verified the effectiveness of this method.关键词
