利用Lyapunov指数方法,验证了一类离散广义Logistic模型存在混沌现象,并采用混沌控制中OGY方法的基本思想,研究了这类模型的混沌控制问题,得出了消除混沌,保持种群稳定到不动点和2-周期轨道的充分条件.
This paper shows that a discrete singular Logistic model has chaotic behavior, and studies the chaos control of the model by using the idea of OGY method in chaos control. The sufficient conditions of getting rid of chaos and keeping population on equilibrium and 2- orbit-period are obtained.
