通过对电压解耦矢量控制系统的研究,介绍了以SVPWM算法为核心的矢量控制系统。文章详细分析了电压解耦矢量控制理论和整个控制系统的仿真框图,并在Matlab/Simulink中对该矢量控制系统进行了仿真建模。在完成整个控制系统的搭建后分别就控制系统、系统调速及突加、突减负载转矩进行了多组仿真实验,并对实验波形进行了分析。仿真结果表明:该系统具有良好的调速性能,系统的静、动态性能良好。

The paper introduced a vector control system taking algorithm of SVPWM as the core by research on the voltage-decoupling vector control system, described the theory of voltage-decoupling vector control and simulation block-diagram of whole control system, and modeled the vector control system with Matlab/Simulink software. After modeling the whole control system, several experiments for control system, speed-regulation of system and load torque suddenly applying and removing were implemented, and the experiment waveform were analyzed. The simulation results showed that the system not only has good capability of speed-regulation, but also good dynamic and static performance.
