In this paper, a novel distributed multi-functional finite-time secondary control strategy is proposed for islanded AC microgrids. The control objective features two key modules: 1) A consensus-based distributed controller aims to achieve frequency restoration and accurate sharing of active power in finite time. 2) A containment-based distributed controller achieves a better trade-off between voltage regulation and reactive power sharing. In addition, for this control method, the centralized controller is not required and only communications among adjacent controllers is able to meet the control requirements. Furthermore, Lyapunov proofs are given to explain the upper boundary of the convergence time. Finally, a cyber-physical microgrid platform is used to verify the proposed controller's effectiveness considering cases of load variations and voltage boundary changes.
