Simulation design of duffing system based on singlechip microcomputer

In order to solve the parameters´ adjusting difficulty of the continuous Duffing chaotic system, a method of using single-chip microcomputer to realize Duffing chaotic system is proposed in this paper. It is proven that the discrete Duffing chaotic system as well as the continuous system has the ability of signal detection. The simulation results based on singlechip microcomputer under MATLAB environment show that this method is feasible to adjust the parameters of the discrete Duffing chaotic system by software, and Duffing chaotic system based on single-chip microcomputer can detect the multi-frequency sine signals.
