| 英文摘要 | when the robot loads force on space station transfer mechanism, there exist some issues such as unstable robot force control system, insufficient load accuracy, and long settling time. To solve these problems, a strategy for adjusting the admittance controller parameters adaptively is proposed. Firstly, the relationship between force and position is established according to the admittance control theory. And a force tracking/force loading controller based on the rectangular coordinate system is initially designed. Then, the parameters of the load transfer mechanism model are identified based on the loading experiment data by the least square method, and the relationship between force and position of robot in specific workspace is established. Finally, the parameters of the admittance controller are adaptively adjusted to make the robot dynamics model approximately match with the dynamic model of the load transfer mechanism. The real-time spatial loading force imposed by the robot on the end of the load transfer mechanism after spreading is realized. The experiment shows that the tracking error of the robot relative to the load transfer mechanism is less than 0.1 mm, and the loading force error is less than 1%, and the robot meets the requirement and provides a real equivalent space load for the space station transfer mechanism. © 2019 IEEE. |
