This letter proposes a switching-fault ride-through controller (SFRTC) for the grid-side converter of permanent magnetic synchronous generator-based wind turbines. The SFRTC switches between an observer-based bang-bang funnel controller (OBFC) and a vector controller via a state-dependent switching scheme. The design of OBFC does not rely on accurate system information, and it works with the estimates of high-order dynamics of system outputs obtained with a high-gain observer. The fault ride-through control performance of SFRTC was studied with hardware-in-the-loop experiments.

通过基于观察者的 Bang__ang 漏斗控制切换 GSC 的故障穿越


这封信提出了一种用于永磁同步发电机风力涡轮机网侧变流器的开关故障穿越控制器（SFRTC）。 SFRTC 通过状态相关切换方案在基于观测器的开关漏斗控制器 (OBFC) 和矢量控制器之间切换。 OBFC 的设计不依赖于准确的系统信息，它与通过高增益观测器获得的系统输出的高阶动态估计一起工作。通过硬件在环实验研究了SFRTC的故障穿越控制性能。
