一种改进型PMSM弱磁控制策略的研究
Research on Improved Flux Weakening Control Strategy of PMSM
摘要
Abstract
PMSM is a nonlinear and strongly coupled multivariable system. The control system is easily influenced by external disturbances or changes in the internal parameters of the motor. Based on the analysis of the flux weakening scheme of the traditional PI controller,the PMSM combined the fuzzy intelligent control theory with the simplified SVPWM overmodulation algorithm was introduced into the flux weakening control system of permanent magnet synchronous motor to realize the output of the full range inverter voltage and improve the stability and anti-interference ability of the system. Aiming at the shortcoming that the quadrature axis current lags behind that of the direct current by adding the negative direct current to the direct axis,the weak magnetic control method was proposed to keep the direct current and the quadrature axis current change at the same time,keeping the current track flat. Finally,the effectiveness of the system algorithm was verified by simulation analysis and experimental analysis.关键词
