中文摘要：
在分析了PMSG（永磁同步发电机）风力发电系统数学模型的基础上，以额定风速以下风能的最大捕获为目标，采用最优跟踪控制方法在系统不同工作点处设计了最优跟踪控制器，采用了一种能够保证稳定性的差值方法以插值增益调度的形式构成PMSG风力发电控制系统，并在Matlab中建立了PMSG风力发电控制系统的仿真模型。仿真结果表明，最优跟踪增益调度控制方法在额定风速以下能有效实现风力发电机组的最大风能捕获。
英文摘要：
The third-order nonlinear model of the PMSG-based wind power generation system （WECS） was established. In order to ensure maximum energy capture under rated wind speed, the nonlinear model was firsty linearized around different operating points, and the optimal tracking controller was designed for each operating point. And then a PMSG- based wind power generation control system was obtained using gain scheduling control with a stability preserving interpolation method. Simulation results indicate that the optimal tracking gain scheduling controller can effectively achieve maximum energy capture under rated wind speed.
