文中对文献［１］提出的混沌自适应控制方法中给出的控制强度取值范围的计算方法作出了重要修改，指出了上文忽略的与控制矩阵的复数本征值λ±对应的控制强度，对离散系统只要满足│λ±│＜１亦可控制混沌，且更有效．其次指出对连续性系统仅考虑文献［１］给出的条件是不够的，控制强度还要满足λ±值的实部小于零，即微分方程的李雅鲁诺夫渐近稳定条件才能有效控制混沌。
In this paper, the method of calculating the range of control strength given in [1] is proposed. The control strength corresponding to the complex eigenvalue λ ± of the control matrix, which is neglected above, is pointed out. As long as the discrete system satisfies │λ ± │ <1, it can also control the chaos and is more effective. Second, it points out that it is not enough for the continuity system to consider only the conditions given in [1], and the control intensity must satisfy that the real part of λ ± value is less than zero. That is to say, the asymptotic stability condition of Li Ya-Lun Nuo can effectively control the chaos.
