Abstract

The invention relates to a fractional-order switching chaotic system synchronization circuit. The fractional-order switching chaotic system synchronization circuit consists of three channel circuits, wherein a first resistor in the first channel is connected with the inverse-phase input end of a first operational amplifier and the output end of a third operational amplifier, a second resistor is connected with the inverse-phase input end of the first operational amplifier and the output end of a fifth operational amplifier, a third resistor is connected with the inverse-phase input end and the output end of the first operational amplifier, and a fourth resistor is connected with the output end of the first operational amplifier and the inverse-phase input end of the fifth operational amplifier. A fractional-order switching chaotic system is established, has more complicated dynamic characteristics compared with an integral-order switching chaotic system and has higher application value during secret communication. The synchronization controller circuit is invented for the fractional-order switching chaotic system, and a foundation is laid for application of the switching system in the secret communication.

Description

technical field [0001] The invention relates to a fractional-order switching chaotic system synchronization circuit. Background technique [0002] The whole of the switching system is greater than the "sum" of the modes, so the switching system itself has complexity. Since the switched chaotic system has more complex dynamic characteristics and better pseudo-randomness than the single chaotic system, it can effectively enhance the security performance of chaotic secure communication, so it has attracted much attention. [0003] Circuits for switching chaotic systems of integer order and fractional order using analog circuits have been reported. For example, Li Jianqing, Mei Zengxia, etc. invented the method and analog circuit for automatic switching of four systems of fractional order chaotic systems based on the Chen type system. The reported fractional-order switched chaotic systems only realize switching between systems, and do not carry out synchronous control on switch...
