基于对称最优法的并网变换器电网同步系统控制设计：综合参考

Control design of advanced grid synchronization systems is complex as they are often adaptive nonlinear feedback systems with one or more filtering networks and feedback loops in their structure. This article intends to contribute to addressing this issue. It is shown that the phase or frequency estimation loop of many advanced grid synchronization systems, including $3\phi$ and $1\phi$ phase-lock...
