基于混沌同步的参数识别

Chaotic synchronization-based approach for parameters identification

构造了一个响应系统,使之与参数未知的驱动系统结构相同,并用参数自适应控制法实现同步。在同步态,两系统的参数完全一致,控制器也自动消失,由此可以得到驱动系统的参数。以Rossler系统为例验证了该方案的可行性。

By constructing a response system, which has the same structure as the parameters-unknown drive system, a parametric adaptive control algorithm is adopted to obtain the synchronization. When the synchronization is achieved, the parameters of the response system are in good agreement with those of the drive system, and the parametric adaptive control low will automatically disappear at the same time. As a consequence, the parameters of the drive system are readily to be determined. Rossler system is used as an example for detailed description. Numerical simulations show the feasibility of the proposed control strategy.
