摘　　要：研究了基于端口受控哈密尔顿模型(PCH)的永磁同步风力发电系统的无源性控制(PBC)问题。在对风力发电控制系统设计中,充分利用其本身的物理结构特性,选择系统能量函数,并基于哈密尔顿方程,建立系统的端口受控哈密尔顿结构模型,基于此模型设计了风力发电系统的无源性控制器,该控制器不仅简单易实现且反映了系统内部结构以及动态特性的信息。同时,在控制器设计中还考虑了系统存在参数不确定和外界干扰情况下的自适应控制问题。仿真实验证明了控制器的有效性。The passivity-based control （PBC） for permanent magnet wind turbine system was studied based on portcontrolled Hamihonian （PCH） model. A passivity-based controller was designed for wind turbine systems based on the PCH model by taking full advantage of the physics structure of wind turbine system and choosing energy function based on Hamihonian equation. This controller is not only simple but also reflecting interior structure and dynamic characteristic of system. In addition, an adaptive controller was investigated under the uncertain parameters and the external disturbance. The proposed controller was proved valid by the simulation illustration.
