Asymptotic false discovery control of the Benjamini-Hochberg procedure for pairwise comparisons

引用

Science China Mathematics 2024年

作者： Weidong liu Dennis Leung Qiman Shao School of Mathematical Sciences Shanghai Jiao Tong University School of Mathematics and Statistics University of Melbourne Department of Statistics and Data Science SICM Southern University of Science and Technology

In a one-way analysis-of-variance(ANOVA) model, the number of pairwise comparisons can become large even with a moderate number of groups. Motivated by this, we consider a regime with a growing number of groups and prove that, when testing pairwise comparisons, the Benjamini-Hochberg(BH) procedure can asymptotically control false discoveries, despite the fact that the involved t-statistics do not exhibit the wellknown positive dependence structure required for exact false discovery rate(FDR) control. Following Tukey's perspective that the difference between the means of any two groups cannot be exactly zero, our main result provides control over the directional false discovery rate and directional false discovery proportion. A key technical contribution of our work is demonstrating that the dependence among the t-statistics is sufficiently weak to establish the convergence result typically required for asymptotic FDR control. Our analysis does not rely on conventional assumptions such as normality, variance homogeneity, or a balanced design, thereby offering a theoretical foundation for applications in more general settings.

Adaptive Third-Order Fixed Time Sliding Mode Control with Chattering Free for Mobile Loading Arm Systems

引用

Journal of Systems Science & Complexity 2024年

作者： WANG Baigeng LI Shurong liu Zhe School of Artificial Intelligence Beijing University of Posts and Telecommunications State Key Laboratory of Industrial Control Technology Zhejiang University

The mobile loading arm(MLA) system is one of the most important mechanical equipments in the petrochemical industry consisting of rigid pipelines and rotating elbows. This paper researches the problems of dynamical modelling and tracking control. At first, an MLA dynamic model is built by using Euler-Lagrange function. And then, an adaptive third-order fixed time sliding mode(FDTSM) tracking controller with chattering free is represented, which enables the MLA system to dock with the vehicle tank mouth. In this paper, a new double-layer third-order fixed time sliding mode controller is first proposed to address the tracking problem in model-based MLA systems with known parameters. Moreover, considering the presence of modeling uncertainty and external disturbances,a nerual network adaptive FDTSM controller is designed to ensure that the close-loop system state tracking error converges to a bounded region around zero within a fixed time. Further, the stability of the close-loop system is proven by using the Lyapunov stability theorem. Simulation results illustrate the validaty of the controller.
