Without substantial compensation, conventional phase-locked loops (PLLs) and estimators might suffer a loss of synchronization with the rotor position. This paper presents an enhanced PLL (EPLL) for ...

In this paper, we first propose a new design strategy of 2D Z-complementary array quads (2D-ZCAQs) with feasible array sizes. A 2D-ZCAQ consists of four distinct unimodular arrays satisfying zero 2D ...
