Field-weakening technology is important for permanent magnet synchronous machine (PMSM) control in wide speed range applications. This paper presents a novel field-weakening control method for permanent magnet synchronous motor to improve maximum speed range and power range, based on discrete-time complex current control and voltage control. The effectiveness of the proposed method is confirmed by computer simulations and experiments.
