一种用于虚拟接地三相LCL并网逆变器的改进级联边界无差拍控制

Cascaded boundary-deadbeat controller has been proven to be effective in controlling single-phase grid-connected inverter with LCL output filter. Such architecture mitigates filter resonance and offers good stability under stiff- and weak-grid conditions. However, its merits are offset by requiring many sensors, dedicated control loop to regulate the operating frequency, and high-precision intracy...
