复杂多个体系统领导者—跟随一致性研究

讨论了强连通网络拓扑情况下的领导者—跟随一致性问题,在跟随者的一致性协议中引入了聚合项,运用李亚普诺夫稳定性理论分析了闭环系统的稳定性,研究发现聚合项的引入对多个体系统达到一致具有重要影响,即增大聚合增益能使跟随者快速跟踪上领导者,从而提高系统的跟踪性能。最后给出仿真例子对理论分析进行了验证。     

Study on the Generation of Ultra-Wideband (UWB) High Power Microwave

The experimental study of ultra-wideband (UWB) technology, its generation and on-line measurement are presented. An experimental repetitive UWB system is designed, manufactured, and tested. High-pressure spark gap switch and its components, as well as oil spark gap switch are studied experimentally on the system. Experimental results indicate that the system operates at a 200 pps repetitive rate with a stable performance. 100 MW peak power UWB pulses are obtained on the system. Fast-time response capacitive divider is designed and fabricated, allowing for an accurate measurement of the high power UWB signal. The main issues related to the design of the switch and the UWB signal online measurement are discussed.
