摘要
基于 L yapunov稳定性理论 ,提出一种具有不匹配参数混沌系统的同步控制方法。即使在有较大参数误差的情况下 ,只要选择合适的反馈控制律和参数自适应律 ,也能保证同步系统的全局稳定性。与已有的结果相比 ,该方法能克服较大参数误差对同步的影响。 L orenz系统和 Chen系统的数值仿真验证了该方法的有效性。
Based on the rigorous Lyapunov stability theory, a method of synchronizing chaotic systems with mismatched parameters is proposed. Feedback control law and parameter adaptive law can be chosen suitably such that the global stability of synchronization system is ensured even if there exist higher parameter errors between driving system and response system. Compared with the existed results, the method can overcome the effect of mismatched parameters. Numerical simulations of Lorenz and Chen systems verify the effectiveness of the method.
