Mean-square consensus control of multi-agent systems driven by fractional Brownian motion

Science China(Information Sciences) 2024年第11期67卷 361-362页

作者： Xiaolin yuAN Yongguang yu Wei SU Guojian ren School of Mathematics and Statistics Beijing Jiaotong University

In the 1940s, the stochastic process with long memory was first proposed by Kolmogorov. Then, Mandelbrot et al. [1]named it fractional Brownian motion(FBM) and studied its properties. The nonlocality, non-Markov property, and long-memory property of FBM allow for a better description of the complex dynamic behavior observed in the real world. In recent decades, the rapid development of FBM has resulted in clear applications in various research fields such as hydrology, climate, wavelet analysis, and finance.
