Chaotic characteristics and circuit implementation in ime-delay feedback Lorenz system
时滞反馈Lorenz系统的混沌特性及其电路实现

The realization of the time-delay function by analog circuit is the crucial work in a Lorenz system with time-delay state feedback. Digital circuit implementation possibly induces pseudomorph because of the data conversion precision. A simple solution to this problem is presented in this paper, and the time-delay state feedback Lorenz system is constructed by adding this analog circuit to the Lorenz system. More complicated chaotic attractors can be generated, and the complex dynamics of system is confirmed by numerical simulation and analog circuit implementation.
