In the paper, a novel four-wing chaotic system was constructed based on a Lorenz-like system. The novel chaotic system had rich dynamic characteristics such as four-wing attractors, widely chaotic regions, high SE complexity, and multiple transient transitions. Meanwhile, the weak chaotic attractors with single-wing and double-wing can be observed through changing the system parameters. NIST tests showed that the system had high complexity, which will have a good application value in secure communication and cryptography. In addition, a corresponding hardware analog circuit was designed based on the novel chaotic system with operational amplifiers and multipliers. The experimental results were agreed with the theoretical analysis, which verified that the novel chaotic system was practical feasibility.

论文基于类洛伦兹系统构建了一种新型四翼混沌系统。这种新型混沌系统具有丰富的动力学特性，如四翼吸引子、广泛的混沌区域、高SE复杂性和多重瞬态转变。同时，通过改变系统参数，可以观测到单翼和双翼的弱混沌吸引子。NIST测试表明该系统具有较高的复杂度，在安全通信和密码学方面具有良好的应用价值。此外，基于带有运算放大器和乘法器的新型混沌系统，设计了相应的硬件模拟电路。实验结果与理论分析相吻合，验证了该混沌系统的实际可行性。
