核电站蒸汽发生器水位常因多种干扰而具有不确定性,因此传统线性水位控制系统较难满足核电站运行要求。针对具有一定不确定性的核电站蒸汽发生器水位模型,根据其特性,借助线性矩阵不等式(LM Is)设计状态反馈H∞控制器、基于极点配置的H∞控制器以及H∞跟踪控制器。在不同稳定工作点下通过仿真试验对上述控制器的效果进行验证和比较,得出了不同稳定工作点下控制策略的特性。

The steam generator water level of nuclear power station often suffers from various uncertainties ,which challenges conventional linear water level control systems in meeting qualified safety and economic operation demand . In this paper , the state feedback H∞ controller ,the pole placement H∞ controller and the H ∞ tracking control‐ler were designed with linear matrix inequalities (LMIs) for steam generator water level control system in nuclear power station with uncertainties .Simulations were carried out for validation and comparison at different steady operating points and characteristics of corresponding control strategy were obtained .
