This invention discloses an airborne tree branch cutting control method based on force feedback, relating to the fields of power line channel maintenance and aerial robot contact operation control technology. The method includes collecting contact force component data, armature current data, and feed acceleration data during the cutting process; obtaining an estimated environmental equivalent stiffness using an environmental stiffness observation model; outputting the tree branch fracture probability using a fracture prediction model; mapping desired damping and desired stiffness using an adaptive impedance control architecture; and calculating adaptive position commands for the flight platform and torque limiting commands for the cutting motor. This invention uses the environmental stiffness observation model and fracture prediction model to perceive the tree branch's flexible deformation and fracture trend in real time. It uses the adaptive impedance control architecture and admittance control law to suppress the flight platform's forward momentum at the moment of tree branch fracture and uses current energy spectral density to identify micro-flutter spectrum characteristics in advance to adjust torque and prevent jamming, achieving precise and safe cutting in unstructured high-altitude environments.
