Abstract
AbstractWe propose a distributed event‐triggered dynamic average consensus (DAC) scheme with a time‐varying threshold for a multi‐agent system (MAS) in a directed graph. In this scheme, each agent is not required to monitor its neighbors in real time, and a threshold is chosen related to consensus performance directly in an MAS, where the threshold is adjusted adaptively according to average consensus performance. Also, we introduce a bounded and monotonically increasing function in a time‐varying threshold, and this function is for guaranteeing the value of a threshold to locate in an appropriate range. Stability analysis shows that the tracking error is eventually bounded and the MAS achieves DAC without Zeno behaviors. Furthermore, the proposed event‐triggered DAC scheme is applied to voltage restoration and adjustable current sharing in DC microgrid. The effectiveness of the proposed scheme is verified by two examples.
