Abstract

The invention mainly aims to provide a power output device, a control method, a joint actuator and an execution assembly, and the power output device comprises a plurality of output parts which are coaxially arranged, and a driving assembly, a feedback assembly and a control assembly which are matched with the output parts. Specifically, the first output piece is provided with a first encoder, the encoder detects the rotation state of the first output piece and outputs the rotation state to the control assembly, and a closed-loop feedback link is established; the second output piece which sleeves the first output piece is additionally provided with a rotating piece which is in transmission connection with the second output piece, and a second encoder is arranged on the rotating piece to detect the rotating state of the second output piece and output the rotating state to the control assembly, so that a shift shaft closed-loop feedback link is established. And the control assembly adjusts the operation of the driving assembly according to the detection information of the encoder and the real-time control signal of the upper computer signal, and further adjusts the rotation of one or more output pieces so as to realize the closed-loop control of the whole power output device.
