Abstract

The invention relates to a chaotic synchronization control method, and belongs to the field of nonlinear science. According to the chaotic synchronization control method, a training sample number setis obtained by solving a main system, a fitness function of the main system and a fitness function of a slave system are established by combining the slave system and an unbiased least square supportvector machine, and a hybrid synchronization trajectory and a control input signal are obtained; and parameters of a kernel function used in unbiased least squares are obtained through a particle swarm algorithm to obtain optimal parameters, and then hybrid synchronous control of the master and slave systems is achieved by using the designed control input signal. According to the chaotic synchronization control method, the calculation mode can be simplified, and the calculation precision is effectively improved.

Description

technical field [0001] The invention belongs to the field of nonlinear science, and in particular relates to a chaos synchronization control method. Background technique [0002] Since the second half of the 20th century, nonlinear science has developed vigorously. Due to the complexity of natural phenomena and social phenomena, it is difficult to describe their dynamic laws with linear dynamic equations, so it is necessary to describe them with nonlinear dynamic equations. On the other hand, the miniaturization of computers provides favorable conditions for scientists to study nonlinear systems. Except for a few nonlinear equations, analytical solutions generally do not exist. It is found that a system described by a deterministic nonlinear evolution equation may enter a bifurcation and enter a dissipative system with an orderly space-time order and lower symmetry when the parameters of the system are changed when it is far from equilibrium, or for A more chaotic state o...
