内置式永磁同步电机新的深度弱磁策略
A novel depth field-weakening strategy for interior permanent magnet synchronous motor
摘要
Abstract
By combining the field-weakening control principle of interior permanent magnet synchronous motor (IPMSM) with the space vector pulse width modulation(SVPWM) and MTPV control principle, a novel field-weake-ning control strategy for IPMSM was proposed in this paper. In the first phase of the field-weakening, the difference between the reference voltage updated by current regulator and the saturated voltage output by SVPWM is used for field-weakening control, which modifies the direct axis of stator current. This method makes full use of the DC bus voltage, and can naturally smooth transition; In the second phase of the field weakening, the principle of MTPV con-trol is used for field-weakening control, and then, being linearized, Compared with the traditional method, this meth-od solves the problem of depth weakening of IPMSM. Between the two stages, the turning speed is used for switch condition to achieve the smooth transition for the first stage to the second stage. The effectiveness and correctness of the proposed field-weakening control method and calculation method were verified with simulation results.关键词
