Abstract：To obtain the rotor position of permanent magnet synchronous motor (PMSM) driving system accurately, this paper proposes a realization scheme of all-digital resolver-to-digital converter (RDC) integrated with online fault diagnosis and fault-tolerant control. The proposed scheme uses a digital sine wave generator to generate the excitation source of RDC, then, the finite impulse response (FIR) digital filter is selected to realize frequency-shifting demodulation of resolver’s orthogonal output, and then, the double synchronous decoupling phase-locked loop is integrated with fault diagnosis and fault-tolerant control to obtain the rotor position and speed of PMSM driving system. At last, the system performance of proposed all digital RDC is tested and conclusions are shown.
