| 摘 要： | 以双馈风力发电机组(DFIG)为研究对象,推导了其dq轴数学模型. 根据某2MW主流双馈电机实际参数,论证了在某些参数及工作条件下会出现混沌运动. 基于主动控制思想,设计了一种主动滑模控制器,使得从任意初始条件出发均能保证系统稳定. 基于Lyapunov稳定性理论分析了系统稳定性. 以双馈电机模型为例进行数值仿真验证,较快的实现了混沌系统同步. 仿真结果表明该控制方法具有良好的鲁棒性和稳定性.

| Abstract: | The doubly fed induction generator (DFIG) is investigated. Its mathematical model under d-q axis is deduced. According to 2MW mainstream DFIG actual parameters the chaotic behaviors are demonstrated to appear in a certain range of parameter values or under certain working conditions. Based on active control method, an active sliding mode controller is designed, which enables chaotic systems to be stablized under arbitrary initial conditions. The stability of the controlling method is analyzed by Lyapunov stability theorem. Finally, numerical results are presented for the DFIG system. This method may realize the chaos synchronization, and both the stability and the robustness are good. |
