Embodiment 1

[0031] Such as figure 1 As shown, the present embodiment provides a complex network distributed pulse synchronization method based on the parameter variation method, including the following steps: Step S1: consider a class of follower network and confirm its leader node; Step S2: obtain each node by a sensor State information and set up the error network model; Step S3: return the state information of each adjacent node and arrange the distributed negative feedback controller; Step S4: the distributed negative feedback controller is affected by the pulse disturbance, and judges the pulse according to the disturbance type Whether it plays a positive or negative role, when the pulse plays a positive role, a new pulse controller is generated to control the network at the same time as the distributed negative feedback controller. Synchronization is achieved under the dynamic balance of the controller and the new pulse controller; when the pulse reacts, a new pulse disturbance is g...

Abstract

The invention relates to a complex network distributed pulse synchronization method and system based on a parameter variation method. The method comprises the following steps: considering a kind of follower network and confirming leader nodes of the follower network; obtaining state information of each node through a sensor, and establishing an error network model, so that a state information vector and a tracking state information vector of each node in the network can be obtained; and returning the state information of each adjacent node, and arranging a distributed negative feedback controller, wherein the distributed negative feedback controller is influenced by pulse disturbance, and judging whether the pulse acts positively or negatively according to the disturbance type. Due to thefact that the performance of the controller when the pulse effect plays a positive role and the performance of the controller when the pulse effect plays a negative role are discussed respectively, limitation is reduced; and due to the fact that a discrete control method is used, a new pulse controller is designed, and the cost can be effectively reduced while the control effect is guaranteed by generating the effect only at some moments.

Description

technical field [0001] The invention relates to the technical field of complex network synchronization, in particular to a complex network distributed pulse synchronization method and system based on a parameter variation method. Background technique [0002] At present, network discipline has become the focus of research fields and disciplines along with the cross-integration of multiple disciplines such as computer, biology, and control. Among them, the network synchronization phenomenon, as a cluster behavior, has attracted the attention of many researchers. So far, among the latest results published by scholars, continuous-working controllers such as negative feedback controllers and pinning controllers have been widely used to achieve complex network synchronization. However, continuous controllers work for a long time and have high control costs, so they can't reduce the control cost very well, while discrete controllers have less achievements in the application of co...
