摘　　要：基于开环-闭环控制,提出了一种离散动力系统同步方法.系统地论述了该方法的基本原理,指出了该方法在实际应用中应注意的一系列问题.在此基础上,推导出为实现系统同步应采取控制策略的具体形式,并从理论上对其鲁棒性进行了论证.数字模拟结果表明,该方法不仅具有较高的同步效率,而且具有很强的适用性,能够在不同条件下实现两个同类或异类离散动力系统的同步.A synchronization method for discrete-time dynamical systems is proposed based on the open-plus-closed-loop control. Its principle is demonstrated systematically. A series of problems of this method in actual application are pointed out. On the bass, the specific form of control strategy used for two discrete-time dynamical systems to get synchronization is deduced. The robustness of the suggested method is rigorously proved in theoretical aspect. Numerical simulation shows that this synchronization method is not only more efficient, but also very practicable. Under different conditions, it can realize synchronization of two discrete-time dynamical systems with same or different type.
