Abstract

The invention discloses a fractional order chaotic system circuit which comprises four channel circuits. The first channel circuit comprises an inverter U1A, an inverter U2A, a fractional order inverting integrator U3A and a resistor. The second channel circuit comprises an inverter U4A, a fractional order inverting integrator U5A, a multiplier A1 and a resistor. The third channel circuit comprises a multiplier A2, a fractional order inverting integrator U6A and a resistor. The fourth channel circuit comprises a fractional order inverting integrator U7A and a resistor Rw1. The order step of a fractional order chaotic system is accurate to 0.01 (namely from 0.91 to 0.99), nine types of fractional order chaotic system circuits can be realized, complexity of key space is enhanced, concealment is improved, and decoding resistance is enhanced. The fractional order chaotic system circuit is simple in structure, easy for hardware implementation, applicable to chaos experimental teaching for fractional order chaotic circuits, and more applicable to the fields of secrete communication, information safety and the like.

Description

technical field [0001] The invention relates to a fractional order chaotic system circuit and belongs to the technical field of chaotic signal generator design. Background technique [0002] As a complex nonlinear motion behavior, chaos has been widely used in the fields of biology, chemistry, engineering and informatics. Compared with the integer order chaotic system, the fractional order chaotic system is more in line with the actual situation and can more accurately reflect the characteristics of the actual system, so the fractional order chaotic system has higher research value and application prospect. [0003] Designing an efficient chaotic signal generator is an effective measure to improve the security of secure communication. The existing fractional order chaotic signal generator design is often limited to chaotic systems with fractional order from 0.1 to 0.9 (step size is 0.1). However, there are few studies on chaotic systems with fractional order ranging from 0....
