Permanent magnet synchronous motor driving single axis gyroscope stabilized platform could enhance its application domain, especially in speed aspect and acceleration aspect. However, the control method of direct axis current equaling zero limited motor output speed. This paper put forward a method of field weakening vector control for permanent magnet synchronous motor driving single axis gyroscope stabilized platform, which could expand motor running range. Direct axis current given signal depended on field weakening, instead of equal to zero. The simulation experiment result was shown the feasibility and effectiveness of the proposed method. |
