基于载波调制PWM的对称六相与三相PMSM串联系统矢量解耦控制
Vector Decoupling Control of Symmetrical Six-Phase Series-Connected Three-Phase PMSM System Based on Carried-Wave Modulated PWM
摘要
Abstract
For the decoupling control problem of symmetrical six-phase and three-phase PMSM series-connected system,the voltage drop caused by leakage inductance is compensated based on the series system mathematical model in two-phase rotating coordinate system,and expected output of the inverter is obtained based on coordinate transformation and control variable superposition.As for the engineering implementation,limitations of inverter voltage and current are fully considered,a method for allocating DC bus voltage is proposed to improve the reliability of system operation.Experimen-tal results demonstrate that the proposed control strategy is capable of achieving decoupling operation of two motors un-der abrupt changes in load or speed.关键词
