翻译后摘要：本文论述了变速变桨距风力涡轮机的控制系统的设计。这种系统的控制目标主要是确保良好的能量转换性能和降低设备部件的机械应力。针对被控对象的不同工作区域，采用多面体模型描述系统的非线性行为，并通过线性矩阵不等式（LMI）形式设计鲁棒线性变参数（LPV）控制器，以最小化闭环系统的多目标HH 2 / ∞性能.对于每个操作区域，所设计的控制器是鲁棒的植物参数的演变与不断变化的操作条件。控制器的性能进行比较，然后在模拟与增益调度线性二次高斯（LQG）控制器，并被认为是更有效的，特别是缓解机械应力的植物传动系统。
Abstract : The paper deals with the design of a control system for a variable-speed pitch-regulated wind turbine. The control objectives of such system are mostly to ensure a good energy conversion performances and to reduce the mechanical stresses of the plant components. For the different operating areas of the plant, the non linear behavior of the system is described by a polytopic model and a robust linear parameter varying (LPV) controller is designed in order to minimize the multiobjective HH 2 / ∞ performance of the closed loop system from a linear matrix inequality (LMI) formulation of the problem. For each operating area, the designed controller is robust to the evolution of the plant parameters with changing operating conditions. The controller performances are then compared in simulation with those of a gain scheduling linear quadratic gaussian (LQG) controller, and is seen to be much more efficient especially for alleviation of mechanical stresses on the plant drive train.
