The invention belongs to the technical field of chaos systems, and discloses a high-order novel three-dimensional chaos model and a circuit thereof. The circuit of the high-order novel three-dimensional chaos model comprises three channel circuits. The circuit of the high-order novel three-dimensional chaos model consists of thirty-nine elements, including nine 3554BM operational amplifiers, six multiplying units, three capacitors and twenty-one resistors. The high-order novel three-dimensional chaos circuit disclosed by the invention has a plurality of balance points and a high-order non-linear term, is more complex and abundant in dynamic behaviors, and can be applied to non-linear circuit course experiments. Moreover, the defect that encrypted information of an existing Chaos system isliable to decryption can be overcome, and a basis is laid for the application of a Chaos system.
