一个具有调幅特性的分段线性混沌系统与微控制器实现
A Piecewise-Linear Chaotic System with the Characteristic of Amplitude Modulation and Its Microcontroller Implementation
摘要
Abstract
By changing the quadratic nonlinear terms in Sprott-B chaotic system model to the piecewise-linear terms and introducing the system parameters and constant controller,a new piecewise-linear chaotic system is proposed. The dynamic characteristics of the system,such as symmetry,dissipativity,equilibrium point and bifurcation diagram are analyzed. The study results show that the system can operate stably on chaotic, quasi-periodic and periodic orbits. The constant controller does not affect the dynamic state of the system, but has the function of global linear amplitude modulation to the output signals. Moreover, with discretization to the system equations by improved Euler algorithm,the corresponding experimental verification is performed and the validity of the simulation results is verified through microcontroller MSP430F249.关键词
