中文摘要:

针对传统PI控制下三相并网逆变器的鲁棒性较差的问题，本文首先建立了基于LCL滤波器的三相两电平变流器的端口受控哈密尔顿（PCHD）数学模型，然后根据建立的PCHD模型采用互联和阻尼配置（IDA-PBC）的无源控制方法，设计了无源控制器，通过李亚普洛夫第二方法验证了系统的稳定性，并且为了加强对直流侧电压的控制能力，采用了模糊控制。最后，在Matlab/Simulink中搭建了基于模糊控制的无源仿真模型，验证了该控制策略的鲁棒性和有效性。

英文摘要:

Aiming at the problem of poor robustness of three-phase grid-connected inverter under traditional PI control, this paper first establishes a port-controlled Hamiltonian with dissipation model of three-phase two-level converter based on LCL filter, and then establishes the PCHD model adopts the passive control method of interconnection and damping configuration, and designs the passive controller. The stability of the system is verified by the second method of Lyapulov, and fuzzy control is adopted to strengthen the control ability of the DC side voltage. Finally, a passive simulation model based on fuzzy control is built in Matlab/Simulink, which verifies the robustness and effectiveness of the control strategy.
