Abstract：Based on the discrete mathematical model of surface-mounted permanent magnet synchronous motors (SMPMSM), a predictive current control (PCC) scheme using dead-beat algorithm is proposed. To compensate the loss of current control precision influenced by model error and voltage-source inverter dead-time, two parallel disturbance observers are designed to estimate model uncertainty and the disturbance voltage, and their stability is proved. Experimental results show that, PCC improves dynamic performance of current loop, and disturbance observers can compensate the adverse effects of parameter variations and dead-time to make PCC more robust and have low current harmonics.
