| 摘 要： | 本文研究了基于端口受控Hamilton(port-controlled Hamiltonian, PCH)模型的永磁同步风力发电系统的无速度传感器控制问题. 首先根据风力发电系统本身的物理结构特性, 建立其端口受控Hamilton结构模型, 然后基于此模型设计了系统的全维状态观测器, 得到系统的速度估计, 从而实现了系统无速度传感器控制. 在控制器设计中还考虑了系统存在参数不确定情况下的自适应控制问题, 以及在控制器设计中用状态量的估值直接替代不可测状态量时存在的误差问题. 最后仿真实验证明了控制器的有效性.

| Abstract: | This paper investigates the speed-sensorless control for a permanent magnet wind turbine generator with port-controlled Hamiltonian (PCH) model. The PCH model is built by fully considering the real structure of the wind turbine system. Based on this model, a full-order observer is developed to estimate the rotor speed for realizing the speedsensorless control. The designed controller is adaptive to the parameter variations and can handle the errors caused by substituting the immeasurable state values with the estimated state values. The proposed controller is validated by the simulation experiments. |
