一类复杂网络系统的预设时间实际同步

Practical synchronization at the predefined-time for a class of complex network systems

针对复杂网络系统中的一类模型,基于时间生成器,设计自适应反馈同步控制器,实现此类网络系统在预设时间取得实际同步.此外,在预设时间后,随着时间延续,整个网络系统将实现指数完全同步.其中预设时间与系统初始状态无关.通过数值模拟直观地验证了结果的有效性.

Based on the time base generator,an adaptive feedback synchronization controller is proposed.Under the condition of this controller,a class of complex network systems will achieve the practical synchronization at the predefined-time.In addition,after the predefined-time,the whole network system will achieve exponential complete synchronization.The effectiveness of the results is verified by numerical simulation.
