Hardware implementation of the quadruple inverted pendulum with single motor

引用

Progress in Natural Science:Materials International 2004年第9期 78-83页

作者： LI Hongxing*, WANG jiayin, feng Yanbin and GU Yundong(Department of Mathematics, Beijing Normal University, Beijing 100875, China)

Inverted pendulums are always used to verify some qualities and effect of certain control theory or method. Single or double inverted pendulum control system has been extensively studied for education and research purposes. However how to control a triple inverted pendulum is a difficult problem, which just a couple of control experts can solve including us. Undoubtedly, to implement controlling of a quadruple inverted pendulum is a very difficult problem, but we first successfully accomplished it using variable universe adaptive fuzzy control method in August, 2002. In this paper, a controller for a quadruple inverted pendulum is demonstrated using the variable universe adaptive fuzzy control theory.

关键词： nonlinear systems variable universe adaptive fuzzy control interpolation mechanism of fuzzy control triple inverted pendulum quadruple inverted pendulum.

在伯林特的“美学原论”,即“审美场”理论中,连续性是审美过程中各种要素相互作用的基本原则,进而成为审美经验统一体最终形成的基本原则,在这里连续性发端于伯林特在现象学的基础上对艺术审美而不是自然审美的探讨。进而,在其试图建构的能同时解释传统艺术与当代艺术的参与美学中,连续性与参与性成为这一美学的两大基本原理。因而在环境美学中,不同于绝大多数西方环境美学家对形而上学的排斥,伯林特将连续性上升到了形而上学的高度,并坦言连续性正日益成为其思考的基础。因此,他以一种自上而下的方式,从连续性形而上学到环境审美的“参与模式”,构建了其独特的环境审美理论。

Understanding the local structure and thermophysical behavior of Mg-La liquid alloys via machine learning potential

引用

International Journal of Minerals,Metallurgy and Materials 2025年第2期32卷 439-449页

作者： Jia Zhao Taixi feng Guimin Lu National Engineering Research Center for Integrated Utilization of Salt Lake Resource East China University of Science and TechnologyShanghai 200237China Joint International Laboratory for Potassium and Lithium Strategic Resources East China University of Science and TechnologyShanghai 200237China

The local structure and thermophysical behavior of Mg-La liquid alloys were in-depth understood using deep potential molecular dynamic(DPMD) simulation driven via machine learning to promote the development of Mg-La alloys. The robustness of the trained deep potential(DP) model was thoroughly evaluated through several aspects, including root-mean-square errors(RMSEs), energy and force data, and structural information comparison results;the results indicate the carefully trained DP model is reliable. The component and temperature dependence of the local structure in the Mg-La liquid alloy was analyzed. The effect of Mg content in the system on the first coordination shell of the atomic pairs is the same as that of temperature. The pre-peak demonstrated in the structure factor indicates the presence of a medium-range ordered structure in the Mg-La liquid alloy, which is particularly pronounced in the 80at% Mg system and disappears at elevated temperatures. The density, self-diffusion coefficient, and shear viscosity for the Mg-La liquid alloy were predicted via DPMD simulation, the evolution patterns with Mg content and temperature were subsequently discussed, and a database was established accordingly. Finally, the mixing enthalpy and elemental activity of the Mg-La liquid alloy at 1200 K were reliably evaluated,which provides new guidance for related studies.
