Patent number: 11926063Abstract: The present invention provides a fractional order sliding mode synchronous control method for a teleoperation system based on an event trigger mechanism. The method comprises: establishing a dynamics model for the teleoperation system by considering external disturbance and parameter uncertainty, selecting a master robot and a slave robot, interactively establishing the teleoperation system through a communication network, determining system parameters of the dynamics model, designing a fractional order nonsingular rapid terminal sliding mode surface equation by utilizing a position tracking error and a fractional order calculus, setting a trigger event condition of information interaction between the master robot and the slave robot, designing a self-adaptive fractional order nonsingular rapid terminal sliding mode controller based on the sliding mode, designing a Lyapunov function to carry out stability analysis, proving the boundedness of a closed-loop state signal of the system.Type: GrantFiled: December 3, 2021Date of Patent: March 12, 2024Assignee: Yanshan UniversityInventors: Changchun Hua, Yilu Wang, Yana Yang, Weili Ding, Liuliu Zhang, Shuang Liu, Guanglei Zhao, Wenliang Pei

Patent number: 8511368Abstract: A pipe for use in a geothermal heat exchange system is disclosed that is insertable into a bore hole having a proximal end and a distal end. The pipe has a proximal end, a distal end and an outer wall member. The outer wall member includes an external surface, and an interior surface defining an interior passageway through which a heat exchange fluid can flow. The pipe also includes a divider extending between opposed points of the interior surface for dividing the interior passageway into an inflow passageway for conducting water from the proximal end to the distal end of the pipe, and an outflow passageway for conducting water from the distal end to the proximal end of the pipe. The divider segregates the water in the outflow passageway from the water in the inflow passageway.Type: GrantFiled: May 24, 2008Date of Patent: August 20, 2013Inventors: James Hardin, Changchun Zhang
