研究了直驱风力发电机系统中永磁同步发电机定子参数变化时的鲁棒H∞控制问题.文中针对电流参数变化模型,提出一种不确定descriptor系统的输出反馈H∞控制方法 利用内模原理得到无静差转速鲁棒H∞控制器,以消除空气动力噪声对转速的影响 控制器的综合过程归结为一组线性矩阵不等式的求解问题.仿真结果表明,所提出的控制方法计算简单,具有较好的静、动态性能,扰动抑制效果明显,对定子参数在大范围的变化具有较强的鲁棒性. (Studied the direct drive wind generator system permanent magnet synchronous generator stators robust H ∞ control problem when parameters change the text for the current model parameters, an uncertain descriptor system proposed output feedback H ∞ control methods . Internal use get no static modulus principle differential speed H ∞ controller to eliminate the effects of noise on the speed of the air force integrated process controller boils down to a set of linear matrix inequalities problem solving simulation results show that the proposed method of calculation. simple and has good static and dynamic performance, disturbance rejection obvious effect on the stator in a wide range of parameters has strong robustness.)
