Abstract

SUMMARYSPMSMs (surface permanent magnet synchronous motors) are employed for many industrial applications. SPMSM drive systems should realize a quick torque response and have a wide operating range. For quick current response in the field‐weakening region, a new current control based on final‐state control (FSC) is proposed in this study. FSC settles the state variables in a final state from an initial state with feedforward input during a finite time. In addition, the current response under voltage limit is analyzed by the voltage limit circle of the SPMSM with a transient term.
