摘　　要：在现有脉冲同步方法的基础上,系统研究了一种新的脉冲同步方法———通过可变长脉冲间隔的脉冲控制实现脉冲同步,并加以推广,应用于更广范围的非线性系统。以Lorenz系统为例,得到可变长脉冲间隔实现同步的充分条件,与现有的同步条件相比,条件更为宽松,而且得到的同步脉冲间隔上限更大,最后以数字仿真验证了这些理论的有效性。A new method of impulsive synchronization is presented, which is implemented via impulsive control with varying impulsive intervals, based on the existing synchronization method, and to extend, it can be used for a wider class of non - linear systems. Some sufficient conditions for the synchronization of Lorenz system with the new method are derived. Compared with the existing results, these conditions are less conservative. Moreover, a larger upper bound of impulsive intervals for the synchronization can be obtained. The result is illustrated to be efficient through a numerical simulation.
