发布时间：2018-10-13 20:07
【摘要】：针对恶意软件在信息物理融合系统中传播机理难以描述的问题,利用非线性动力学理论构建其传播动力学模型,并基于稳定性理论和Hopf分岔定理对该模型的复杂动力学行为进行分析.为了控制恶意软件传播所引发的Hopf分岔,根据分岔控制理论设计了一类结合参数调节法与状态反馈法的混合分岔控制策略,并深入研究控制参数对Hopf分岔点位置及极限环幅值的影响.数值仿真结果表明所设计的混合分岔控制策略不仅能够提前或推迟Hopf分岔点,而且可以改变极限环幅值大小,使信息物理融合系统产生预期的动力学行为,实现控制目的,从而有效降低恶意软件的危害.
[Abstract]:Aiming at the problem that the propagation mechanism of malware in information physics fusion system is difficult to describe, the nonlinear dynamics theory is used to construct the propagation dynamics model of malware. The complex dynamic behavior of the model is analyzed based on the stability theory and Hopf bifurcation theorem. In order to control the Hopf bifurcation caused by malware propagation, a hybrid bifurcation control strategy combining parameter regulation and state feedback is designed according to bifurcation control theory. The influence of control parameters on the position of Hopf bifurcation point and the amplitude of limit cycle is studied. Numerical simulation results show that the proposed hybrid bifurcation control strategy can not only advance or delay the Hopf bifurcation point, but also change the amplitude of the limit cycle, so that the information physical fusion system can produce the expected dynamic behavior and achieve the control purpose. In order to effectively reduce the harm of malicious software.
