Description

technical field [0001] The invention belongs to nonlinear circuits, in particular to a new fractional order chaotic circuit. Background technique [0002] The history of fractional calculus theory and integer order calculus theory is the same, but the development of fractional order calculus theory is slower. There are many fractal-dimensional facts in nature, and there are similar phenomena between integers and fractions. Some research results have been achieved in fractional chaos research, such as fractional chaos in chua system, Lorenz system, chen system, and Lü system. The successful application of fractional calculus in chaos makes fractional calculus play an important role as a mathematical tool in solving natural phenomena, and promotes the further development of fractional calculus theory. [0003] The application number is 201020669117.6, and the authorized announcement number is CN201910811U, a utility model patent "a fractional order chaotic circuit", which rea...
