This invention discloses an adaptive impedance control method and device for a teleoperated robot system. The method is based on a fuzzy logic-based intelligent control mechanism. It dynamically generates a correction update rate for online compensation adaptive terms through fuzzy inference, based on real-time acquired master-slave state information and preset control parameters. This correction update rate, real-time state information, and preset parameters are integrated, and the core dynamic equations of the preset impedance control model are solved to calculate the robot's target position within the current control cycle. This method, based on the robot following the operator's hand movements, superimposes a position compensation amount optimized by the adaptive impedance control model. When problems such as operator hand tremor or network transmission delay cause a sudden increase in contact force, making it impossible to effectively track the desired contact force, the adaptive impedance control device adjusts the contact force, achieving refined teleoperation control.
