电光双稳系统中混沌的控制

采用反馈方法研究电光双稳混沌系统的不稳定周期点及分岔点的控制. 根据受控系统的Jacobi矩阵特征值与系统状态间的关系, 确定系统反馈系数, 从而实现对混沌系统不同周期点及分岔点的稳定控制. 数值仿真结果表明: 该方法可实现系统单周期点、 二周期点、 第一分岔点和第二分岔点的稳定控制; 通过在一定范围内调整反馈系数, 可实现如四周期和八周期等多种周期状态的稳定控制.

Chaos Control in Electrical-Optical Bistable Systems

Stabilizing unstable periodic points and bifurcational points of a chaotic electrical optical bistable system were studied by means of the feedback method. Based on the relations between state and the eigenvalue of Jacobi matrix of system, the coefficient can be ascertained, and then the chaos control can be achieved. The numerical calculation result shows that this method can fulfill the stable control of different periodic points and bifurcation points. Simultaneously, with the same method we can realize the stable control of different periodic states, such as periodic points of four, eight and the others.
