| 摘 要： | 建立了三相电压型PWM整流器在d-q坐标系下的非线性数学模型,通过非线性输入变换和引入交、直流侧的功率平衡方程,推得三相电压型PWM整流器的线性化数学模型;由此提出了一种电流内环基于状态反馈解耦、电压平方外环基于功率平衡理论的双闭环矢量控制策略,并进行了Matlab/Simulink仿真验证。最后,对基于6MBP20RH060和TMS320F2812设计制作的样机进行了试验,达到了较好的效果。

| Abstract: | The nonlinearized mathematical model of three-phase voltage source PWM converter was established in d-q coordinates,meanwhile nonlinear input transformation and power balance equation were used to derive a linearized model from the original nonlinearized model.Then a double-loop vector control strategy in which the current inner loop based on state feedback decoupling theory and the voltage square outer loop based on power balance theory were proposed.Furthermore,it was verified by Matlab/Simulink simulation and an experiment of the prototype which was designed based on 6MBP20RH060 and TMS320F2812. |
