摘要针对直流母线采样电机控制系统电压空间矢量脉冲宽度调制问题,分析传统空间矢量脉冲宽度调制（SVPWM）方法的电流采样机理,揭示其在直流母线采样系统中不可观测区域的存在机理,通过定义最小采样时间的概念精确划分出直流母线电流采样不可观测区域,进而通过插入测量矢量和补偿矢量提出直流母线采样电压空间矢量脉冲宽度调制（SSVPWM）方法及其电流重构策略。通过实验验证了所提方法的电流采样误差低于2%、相电流高次谐波含量低于3%、三相电流畸变率低于1.6%,为高性能矢量控制提供了精确的电流测量。

Abstract：Aiming at the voltage space vector pulse width modulation problem of DC bus sampling motor control system, the current sampling mechanism of the traditional SVPWM method is analyzed, and the mechanism of the unobservable region in the DC bus sampling system is revealed. By defining the concept of minimum sampling time, the unobservable area of DC bus sampling system is divided accurately, and then the DC bus sampling voltage space vector pulse width modulation method (SSVPWM) and its current reconstruction strategy are proposed by inserting measurement vector and compensation vector. Finally, the experimental results show that the current sampling error is less than 2%, the higher harmonic content of the phase current is lower than 3%, and the THD of the three-phase current is lower than 1.6%, which provides accurate current for high performance vector control.

Key words： Pulse width modulation DC bus current sampling minimum sampling time phase current reconstruction sampling voltage space vector pulse width modulation (SSVPWM) method
