双馈风力发电系统的滑模变结构控制技术
Sliding Mode Variable Structure Control Technology Used in Doubly-fed Induction Generation System
摘要
Abstract
In order to study the improvement of system performance when the sliding mode variable structure control strategies are used in the doubly-fed induction generation(DFIG)system,a sliding mode variable structure control strategy is proposed based on exponential reaching law. The control rate of different control objects is analyzed and cal-culated,and based on the simulation model of DFIG built in Simulink,the applications of variable structure control to the dual-pulse width modulation(PWM)converter control,maximum power point tracking(MPPT)control and no-load grid-connected control are studied systematically. Compared with the proportional-integral(PI)control method, the simulation result shows that the proposed sliding mode variable structure control strategies not only simplify the con-trol structure,but also improve the response speed,control precision and robustness of the system,indicating their ef-fectiveness and feasibility.关键词
