The invention discloses a signal generator based on chaotic synchronization and anti-synchronization switching. The signal generator comprises a driving unit, a parameter correction unit, a synchronization and anti-synchronization switching unit and a response unit. System parameters of the driving unit are unknown, and the driving unit is used for generating a chaotic driving signal based on a three-dimensional Qi system; the parameter correction unit is used for adaptively correcting the system parameters of the driving unit and the response unit according to the chaotic driving signal and a signal fed back by the response unit; the synchronization and anti-synchronization switching unit is used for controlling the response unit and the driving unit to be in a synchronization state or an anti-synchronization state according to a control instruction; and the response unit is a four-dimensional hyper-chaotic Lu system and is used for implementing synchronization or anti-synchronization with the driving unit under the control of the synchronization and anti-synchronization switching unit. According to the signal generator disclosed by the invention, adaptive synchronization and anti-synchronization control can be implemented on the three-dimensional Qi system and the four-dimensional hyper-chaotic Lu system with the unknown parameters, and rapid switching of synchronization and anti-synchronization is carried out on two systems by utilizing an electronic switch.
Description
technical field [0001] The invention relates to the field of nonlinear systems, in particular to a signal generator based on chaotic synchronous anti-synchronous switching. Background technique [0002] Since Pecora L.M and Carroll T.L pioneered the synchronization of chaotic systems in 1990, chaos synchronization has become a hot topic in the field of nonlinear research. Huge potential applications. In order to effectively experiment the synchronization and control of chaos, many feasible methods have been proposed, such as adaptive synchronization, active-passive synchronization, coupling synchronization, projection synchronization, linear feedback control and sliding mode control, etc. However, most of the current researches on chaotic synchronization focus on the systems with the same structure or the same dimension, and the research on the synchronization between chaotic systems with different structures is rare. From the perspective of future development trend, the s...
