| 摘 要： | 针对U型管蒸汽发生器的给水阀开度-水位动力学特性随其本身和给水泵运行工况改变而变化的特性，建立了能定量描述上述原因导致的参数摄动和未建模动态的给水阀开度-水位对象的不确定状态空间模型。基于结构奇异值综合方法设计蒸汽发生器水位鲁棒控制器，并通过选择合适的性能加权函数优化控制系统的鲁棒性能。仿真结果表明，所设计控制器可满足蒸汽发生器从零负荷至满负荷及各种给水泵运行工况下水位自动控制的要求，具有较好的控制品质。

| Abstract: | An uncertainty kinetic model for valve position of feed water to steam generator water level plant was built which can quantitily express parameter perturbation and unmodeled dynamic due to operation condition change of steam generator and feed water pump.Robust controller was designed based on structured singular value synthesis method.Robust stability of the water control system can be guaranteed under parameter perturbation and unmodeled dynamic,and robust performance can be acquired via suitable performance weight function.Simulation results show that good control performances are obtained under all combinations of steam generator operation condition and feed water pump operation condition. |
