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.)

光伏电池阵列输出功率受光照强度和温度变化的影响，因此最大功率点跟踪（MPPT）技术广泛应用于光伏系统中。在所有最大功率点(MPP)控制策略中，扰动观察（P&O）MPPT算法因易实现被广泛应用，然而它的缺点是在稳定工作状态下工作点通过MPP 时会导致能量振荡损耗，并且在光照强度或温度发生突变时表现较差的动态响应。在本文中，提出一种改进型变步长扰动观察MPPT 算法，此方法依据工作点动态调整步长变化，与传统固定步长方法比较，本文提出的方法(Photovoltaic array output power is affected by light intensity and temperature change, so the maximum power point tracking (MPPT) technique is widely used in light volt system.In all of the maximum power point (MPP) control strategy, the disturbance observation (P&O) MPPT algorithm is widely used because of easy to implement, but its drawback is that under the steady working state working point by MPP will cause energy loss of oscillation, and the mutations in poor light intensity and temperature of dynamic response.In this article, the paper puts forward a modified variable step disturbance observation MPPT algorithm, this method is based on the working point dynamic adjustment step change, compared with the traditional fixed step length method, the proposed approach)
