考虑非观测区补偿的永磁同步电机单电阻采样重构
Single Resistor Sampling Reconstruction of Permanent Magnet Synchronous Motor Considering Non-Observation Area Compensation
摘要
Abstract
To further realize the low cost, small size and high performance of permanent magnet synchronous motor (PMSM) vector control, a novel three-phase current reconstruction method based on single current sensor is proposed. The principle of three-phase current reconstruction technique is studied, and the relationship between DC-bus current and phase currents of SVPWM controlled three-phase inverter is set up in different voltage vectors combined with the motor drive system. The region in which the phase current is unable to reconstruct is defined as non-observation area. Through adjusting the duty ratio of SVPWM, a novel method using the non-observation area compensation for solving the problem of reconstruct phase current in non-observation area is proposed. The comparisons of experimental results verify the validity and reliability of this method.关键词
