| 中文摘要: |
| 针对风力机叶片颤振系统，提出了一种结合分数阶（Fractional Order）控制与内模控制（Internal Model Control,IMC）的新型颤振控制方法。利用分数阶滤波器设计了分数阶内模控制器，基于闭环动态特性指标，如相位裕量和截止频率，实现对控制器参数的自整定。通过仿真实验对比证明,针对风力机叶片颤振控制，所设计的控制方法优于传统PID、内模PID控制方法，不仅减少了控制参数，而且提高了动态特性和鲁棒性。 |

| A new flutter control method combining fractional order control and internal model control (IMC) is proposed for wind turbine blade flutter system.The fractional order IMC is designed by using the fractional order filter.Based on the closed loop dynamic characteristics,such as phase margin and cut off frequency,the controller parameters are self tuning.The simulation results show that the designed control method is superior to the traditional PID and internal model PID control methods for wind turbine blade flutter control.It can not only reduce the control parameters,but also improve the dynamic characteristics and robustness. |
