基于相位补偿法的永磁同步电机单电流传感器矢量控制研究
Research on PMSM single current sensor vector control based on phase compensation method
摘要
Abstract
In order to solve the problem that the current reconstruction of permanent magnet synchronous motor(PMSM)control system using single current sensor vector control algorithm is easy to produce reconstruction blind area,which leads to current reconstruction failure in some areas,an improved current reconstruction technology based on phase compensation is proposed.The pulse position is modulated without affecting the amplitude of the synthesized voltage vector,and the reconstructed current is compensated at the voltage sector boundary,which not only eliminates the current reconstruction blind area,but also inhibits the reconstructed current distortion at the voltage sector boundary.In comparison with the traditional method,the simulation results show that the reconstruction current obtained by the proposed method is closer to the actual current value,the reconstruction current error is smaller,the system control performance is improved,and the feasibility and reliability of the proposed method are verified.关键词
