In this paper. on the basis of the three-dimensional Chen system. a smooth continuous nonlinear flux-controlled memristor model is used as the positive feedback term of this system. a hyper-chaotic circuit system is successfully constructed. https://www.spidertattooz.com/Metabo-HPT-NT1865DMASTM-18V-MV-15-Gauge-Brushless-Cordless-Angled-Finish-Nailer/
