英文摘要：

To improve the performance of a micro-operational force intelligent assist device （IAD） based hoisting system, the end-effeetor, the device at the end of the robotic arm, was redesigned to improve interaction with the environment. The working principles of the end-effeetor were analyzed and on that basis a velocity control strategy and a displacement-increment control strategy were proposed. Using the dSPACE simulation platform, micro-operational force hoisting systems were studied. The results showed that both a velocity control strategy and a displacement-increment control strategy are feasible, and when micro-operational force was applied, the hoisting system adapted to human operation, effectively assisting movement of loads up and down. This should meet the compliance requirements of an IAD for operator assisted hoisting of loads.
