  • Publication number: 20240141929
    Abstract: This invention discloses a pneumatic and cable-driven hybrid artificial muscle, comprising pneumatic actuator, pneumatic pressure regulating assembly, and cable drive assembly. The pneumatic pressure regulating assembly is connected to the pneumatic actuator to regulate air pressure in the pneumatic actuator for controlling the pneumatic actuator to extend or contract. The cable actuation assembly comprises a cable fixedly connected to the pneumatic actuator for controlling the pneumatic actuator to contract. In this invention, the artificial muscle employs a dual pneumatic and cable actuation mechanism. By leveraging the inherent stiffness of the pneumatic actuator, it can provide substantial actuation force for joint movement. Simultaneously, the cable actuation assembly can provide significant pulling force, effectively ensuring safety in human-machine interaction and offering sufficient bidirectional aiding force to individuals with disabilities who use the artificial muscle as an aiding actuation device.

    Abstract: A line current iM(k0) of an M side of a first direct-current transmission line is collected at a moment k0. A line current iM(k0?ts) thereof is collected at k0?ts. At a moment k0, a differential value diM(k0) of a current of the side of the first direct-current transmission line is calculated according to the line current iM(k0) and the line current iM(k0?ts). It is determined whether the differential value diM(k0) of the current meets a protection enabling criteria. If so, direct-current protection for the M side of the first direct-current transmission line is enabled. A line current iM(j) of the M side of the first direct-current transmission line is collected at a moment j. A line current iM(j?ts) thereof is collected at a moment j?ts. A differential value diM(j) of the current of the M side of the first direct-current transmission line at the moment j is calculated according to the line current iM(j) and the line current iM(j?ts).
