Abstract

In order to achieve higher speed range over base speed, a proposed field-weakening control method of PMSMs is introduced in this paper. Only one current regulator based on controlling the amplitude of current vector is used for deep flux-weakening control. At the same time, the proposed control can be applied in square-wave mode where output voltage of inverter is constant. Its stability analysis is presented by small signal model. The proposed control method is verified by simulations and experiments.
