“…The fundamental components in the distorted voltage or current (dq theory) are DC quantities in these theories. MFI controllers based on instantaneous active and reactive power theory were studied in [30], [60], [71], [72], [77], [78], [81], [82], [99], [100], [106], [112], [114], [133], [137], [140], [153], [177], and [178], whereas synchronously rotating frame theory-based controllers were studied in [55]- [57], [63], [65], [66], [70], [80], [82], [85], [87]- [89], [101], [103], [104], [107], [118], [120], [129], [139], [148], [150], [151], [162], [165]- [167], [174], and [179]- [182]. Synchronously rotating frame theory has limitation...…”
