基于双dq空间的永磁同步电机无位置传感器起动策略
Position-Sensorless Startup Strategy for Permanent Magnet Synchronous Motor Based on Double dq Space
摘要
Abstract
Current-frequency control (IF control) for permanent magnet synchronous motor (PMSM) independent of the rotor position signal is a position-sensorless startup strategy. However, the transition from IF control to other position-sensorless control strategy is complicated, the scheme transition can cause current oscillation in a short time. Therefore, a novel position-sensorless startup strategy with double dq space is proposed. Two dq spaces are established in virtual synchronous frame and rotor synchronous frame respectively. The state variable and control variable of PMSM are established in the two dq spaces respectively. The transition of two control schemes changes into the transition of two dq spaces. The double dq space corresponds with the same three-phase stationary frame. Thus, the smooth and seamless transition of the two control schemes is achieved . Experimental results have verified this startup strategy.关键词
