摘　　要：采用基于定子侧磁链定向的矢量控制策略来实现最大功率的跟踪,该控制策略是基于功率外环电流内环的双闭环控制方式。在双闭环控制中使用了基于内模原理的控制器,并将基于内模控制的结果与传统的PI控制的结果进行对比分析。仿真结果表明,基于内模原理的内模控制器(IMC)比PI控制器具有更强的补偿时间滞后的能力,响应速度更快,更稳定,抗干扰的能力更强。基于双馈式异步风电机组建立了仿真模型,给出了在PSCAD/EMTDC环境下的仿真结果。The stator flux oriented vector control strategy was used to realize MPPT, and the control strategy was based on power outer loop and current inner loop. PI controller was generally used by the Double loop control, but the IMC was used and the comparative analysis of the result between the PI control and internal model control was given. The simulation results indicate that the IMC is with more strong time delay compensation ability, more fast response speed, more stable and anti-jamming than PI controller. A simulation model of DFIG was built and simulation results on PSCAD/EMTDC platform were given.
