Embodiment Construction
[0060] As shown in the figure, a multi-sensor fusion prosthetic hand grip force feedback control method, the prosthetic hand includes a PD-based CMAC manipulator grip force controller, the control method includes multi-sensor fusion and feedback method, grip force prediction method and based on PD's CMAC manipulator grasping control method;
[0061] In the multi-sensor fusion and feedback method, a sensor array composed of multiple sensors is used to collect feedback signals and sensory signals for the forearm and prosthetic hand, and to fuse the collected signals, including forearm muscle collection related to the hand grasping movement. Its surface electromyographic signal collects the temperature, contact force, sliding state of the object grasped by the prosthetic hand, collects the joint acceleration and angular velocity corresponding to the grasping action, and collects the actual grip force of the grasping action of the prosthetic hand;
[0062] The grip prediction meth...
