Sampled-Data-Based Secondary Frequency Control for Fractional-Order Islanded Microgrid Subject to External Disturbance

Yongjie Shi, Shuxian Fan

The motivation for this paper is that most of the works on secondary frequency control are focused on conventional synchronous communication approaches. To extend this research, this paper investigates the sampled-data-based H∞ load frequency control (LFC) problem for fractional-order islanded microgrids under …

Bipartite Synchronization of Cooperation–Competition Neural Networks Using Asynchronous Sampling Scheme

Shuxian Fan, Yongjie Shi, Zhongliang Wei

This paper investigates the bipartite synchronization problem for cooperation–competition neural networks (CCNNs) under asynchronous sampling control. First, using signed graph theory to characterize the interrelationships between cooperation and competition, a mathematical model for cooperative–competitive neural networks is established. To formulate the error …

Association between hepatic steatosis index and impaired fasting glucose: a multicenter retrospective cohort study in China

Yimei Chen, Jie-Ying Han, Siwen Zhao, Yongjie Shi et autres

Background: The Hepatic Steatosis Index (HSI) is a simple screening tool for adults with non-alcoholic fatty liver disease (NAFLD). While lipid and glucose metabolism are closely interrelated, few studies have examined the association between HSI and impaired fasting glucose (IFG). This study …

Coupling an advanced actuator surface method with CFD for unsteady aerodynamic simulation of helicopter

Tianyi Zhang, Yongjie Shi, Guohua Xu, Yuan Gong et autres

An advanced Actuator Surface Method (ASM) coupled with Computational Fluid Dynamics (CFD) is developed and applied to the complex unsteady aerodynamic simulation of helicopter. By introducing an improved three-dimensional anisotropic Gaussian kernel, this method effectively addresses the severe aerodynamic load fluctuations commonly …
