摘　　要：在蒸汽发生器水位优化控制的研究中,由于蒸汽发生器是一个高度复杂的非线性时变系统,水位不易保持稳定。为解决上述问题,根据线性参数变化理论,建立了时变且参数依赖的多胞线性参数变化模型,用含有H_∞性能的线性二次型调节器(linear-quadratic regulator,LQR)方法,设计了分段变增益跟踪状态反馈控制器。控制器的求解采用线性矩阵不等式技术。仿真结果表明,控制器具有良好的跟踪性能,且能够有效地抑制干扰,控制水位的稳定。Steam Generator is a highly complex nonlinear time-varying system. In this paper, linear parameter varying theory was proposed to build the polytopic linear parameter varying model of steam generator. According to the method of linear-quadratic regulator which contains the H∞ performance, a gain-scheduling tracking controller was designed based on polytopic linear parameter varying model. Linear matrix inequalities technology was used to solve the controller. The simulation results show that the controller has good tracking ability, and can restrain the disturbance effectively.
