| 中文摘要 |
| 针对风力机具有非线性和参数的不确定性的特征, 提出了基于线性变参数(linear parameter varying, LPV)增益调度的风力机主动容错控制方法, 降低故障对机组动态特性的影响. 基于LPV凸分解方法, 将风力机的非线性模型转化为具有凸多面体结构LPV模型, 利用线性矩阵不等式(linear matrix inequalities, LMIs)技术对凸多面体各个顶点分别设计满足性能要求的控制器, 再利用各顶点设计的反馈控制器得到具有凸多面体结构LPV容错控制器. 仿真结果表明, LPV增益调度技术可以成功地应用于风力机系统的容错控制. |
| 英文摘要 |
| In the light of the nonlinear properties and uncertain parameters of wind turbines, an active fault tolerant control technology is proposed to solve the dynamic stability problems, which is based on the linear-parameter-varying (LPV) gain scheduling technology. The linearized model around the operating point of wind turbines and faults is converted into a convex polyhedron structure LPV model by using LPV convex decomposition method. Then, each vertex of convex polyhedron was designed to meet the desired performances by using Linear Matrix Inequalities (LMIs). All the vertex gains are synthesized to build LPV controller with convex polyhedron structure. The simulation result shows that the LPV active fault tolerant controller can be applied to the wind turbines successfully. |
