Abstract

The invention relates to a method for random lag synchronization between coupling networks in a noisy environment. The method comprises the steps of establishing coupling networks containing information transmission delay, constructing a controller in the noisy environment and determining an error network. According to the method provided by the invention, a linear time lag feedback controller is designed based on a white noise feedback gain, so the random lag synchronization between unidirectional coupling networks in the noisy environment is realized. Compared with the control method that is relatively complex and is not easy to realize in complex network synchronization research, the control method is practical, simple and convenient, the unavoidable noise in the real environment is fully used, and the operation energy consumption of the network is reduced.

Description

technical field

[0001] The invention belongs to complex network synchronization technology, in particular to a method for random lag synchronization between coupling networks in a noise environment. Background technique

[0002] The chaotic system is extremely sensitive to the initial conditions, and a small change in the initial conditions will cause its dynamic evolution behavior to vary widely. "A butterfly flapping its wings occasionally in the Brazilian jungle may cause a tornado in Texas." This famous butterfly effect is a true portrayal of chaotic signals sensitive to initial conditions and long-term unpredictability. In addition, chaotic signals also have the characteristics of wide frequency spectrum and noise-like characteristics. These characteristics of chaotic signals made people think that chaos is uncontrollable. In the early 1990s, chaos synchronization control was proposed one after another, which subverted the long-standing traditional idea of ​​"chaos is...
