A control method, the saturation in order to avoid switching state of an inverter

摘要

A control method for preventing an inverter into saturated state:Performing a pi - control in each case to a directly axes - reference current i_dref and a quadrature axes - reference current i_qref, in order to a directly axes - reference voltage v_dref and a quadrature axes - reference voltage v_qref ; adaptation of the directly axes - reference voltage v_dref and the quadrature axes - reference voltage v_qref in accordance with a working of the inverter, in order to directly axes voltage v of a matched_d and an adapted quadrature axes voltage v_q to be obtained, in order to thus the inverter to make it possible in the unsaturated state. The control method according to the embodiments of the present disclosure possible to prevent the inverter operates in a saturated state, a more stable control for a motor and a more effective protection of the inverter providing.
