阐述空间矢量脉宽调制技术用于交流感应电机矢量控制系统的基本原理,讨论了间接转子磁场定向电流注入型矢量控制系统的实现,并对它进行仿真研究。仿真结果表明:这种控制技术可以实现感应电机产生转矩的电流分量和产生磁通的电流分量之间的解耦控制,使感应电机获得与他励直流电机一致的瞬态响应特性,实现对负载扰动和参考值变化的快速响应。

This paper introduced the basic principles of the space-vector pulse width modulation employed in AC induction machine vector control system. The schematic of the indirect rotor-flux-oriented control of a current controlled voltage-source inverter-fed induction machine drive was discussed. Many simulation studies were performed to verify the feasibility of the proposed vector controlled drive. The results indicated that the torque-producing and flux-producing current components were decoupled and the transient response characteristics were similar to those of a separately excited DC machine with this vector control technology of induction machines, resulting in the ability of the system against any load disturbances and reference value variations with quick response.
