摘　　要：为了解决双馈感应电机最大功率追踪困难问题、提高其最大功率追踪效率,提出一种用于双馈感应电机最大功率追踪的多输入多输出二阶滑动模态控制方法 .对双馈感应电机进行建模分析,引入多输入多输出二阶滑膜控制设计过程,简化为含有m个变量的单输入单输出二阶滑膜控制,进而给出双馈感应电机单输入单输出二阶滑膜控制方法;在阶跃风速、随机风速、低电压穿越三种工况下进行仿真分析,验证了控制方法的有效性和鲁棒性.In order to solve the problem of maximum power tracking of doubly-fed induction motor and improve its maximum power tracking efficiency,a multi-input/multi-output(MIMO)second-order sliding mode control(SOSMC)method for maxi⁃mum power point tracking(MPPT)of doubly-fed induction generator(DFIG)was proposed.The model of doubly-fed induc⁃tion generator was analyzed,and the design process of multi-input/multi-output second-order sliding film control was intro⁃duced,and a single-input single-output second-order sliding film control with m variables was simplified.Furthermore,a singleinput single-output second-order sliding film control method for doubly-fed induction generator was proposed.Simulation re⁃sults verify the effectiveness and robustness of SOSMC under three conditions of step wind speed,random wind speed and low voltage crossing.
