摘　　要：针对轴流转浆式双调节水轮机的特点,提出了一种双调节水轮机的优化控制方法,该方法基于状态反馈H∞控制理论,利用求取线性矩阵不等式完成系统优化控制设计.它可以使得在扰动下水轮发电机组的导叶与浆叶的位置按照各自的优化控制规律进行调整,从而使水力过渡过程达到优化.仿真结果表明提出的控制方案可使系统的扰动特性得到明显改善,同时也使系统具有较强的鲁棒性.Considering the charactistcs of an axial-flow Kaplan turbine, an approach is proposed to optimizing the control of Kaplan turbine-generator unit, which is derived from LMIs and based on the state feedback H∞ control. Both the guide vane opening and blade opening of a hydropower generating unit can be separately regulated during disturbance according to the optimal regulation laws thus obtained to optimize the transient process of water flow. Simulation results showed that the proposed approach can obviously reduce the disturbance effect on the system and improve the robustness of the system.
