N2 - In this paper, a field-weakening scheme on modulated model predictive control (M2PC) using predictive current error (PCE) margin is proposed for permanent magnet synchronous motor (PMSM). Compared with traditional finite-control-set MPC, M2PC has small steady-state current harmonics benefitting from the synthesis of multiple vectors. However, due to the limit of inverter output capacity and the discreteness of M2PC, the operation range is difficult to extend the field-weakening region and ensure dynamic performance. To address this problem, a predictive current error (PCE) margin with a weight factor is designed to improve the dynamic performance in field-weakening operation, in which the PCE margin is derived from the voltage mapping. The experimental results are eventually conducted for validating the proposed methods.
