| 摘 要： | 首次采用现代控制理论中的滑模变结构方法研究了无刷双馈发电机(BDFM)运行时有功功率与无功功率的解耦控制,在状态方程的基础上,应用Lyapunov函数求得了有功功率与无功功率的滑模控制律,并在Matlab/Simu-link基础上建立了系统的仿真模型。仿真结果表明,滑模变结构控制能够有效的实现有功功率与无功功率的解耦控制,并实现了风能的最大功率捕获,证明了该控制策略的有效性。

| Abstract: | Brushless doubly-fed machine(BDFM)has good characteristics and wide applications in the wind energy conversion system.Effective control of active and reactive power is crucial to the applications of the BDFM and the power quality.A new robust controller based on sliding mode theory was designed for the decoupled control of active and reactive power of the BDFM.The Lyapunov function was used to get the control laws based on the state equations.The simulation model was developed with the matlab/simulink software.Simulation results showed that active power and reactive power are successfully decoupled controlled and the whole wind energy conversion system can realize the maximum wind energy capture.The good performance of the controller proves the power control strategy's feasibility. |
