| 摘 要： | 由于投影同步算法的比例因子很难预测,因此提出了一种基于控制的改进的混沌投影同步算法。利用Lyapunov稳性定理,使得藕合混沌系统的误差函数快速衰减到零,同时证明该改进算法的可行性。实验表明,改进后的算法比原PS算法更有效。

| Abstract: | A novel synchronization scheme of chaotic system was designed. Since the scaling factor of PS (projective synchronization) is predicted hardly, a control algorithm is thus proposed to improve on the projective synchronization in chaotic system. In this work, the purpose of adopting Lyapunov stability theory is that the error function can vanish quickly. At the same time, deduction for the theorem of novel synchronization shows its availability. The experiment indicates that it's more effect than PS did. |
