摘要：

An H ∞ control approach of the DC microgrid system with uncertain parameters and communication delays is investigated. Firstly, norm bounded uncertainty and delay-dependent model are employed to depict indeterminacy and delays. And the small-signal method is used to establish the microgrid system model. Then, Lyapunov method is adopted to analyze stability of the system and sufficient existence condition of the controller is given in form of linear matrix inequality (LMI). Finally, simulations verify validity of the proposed model and control method. © 2018, Power System Technology Press. All right reserved.
