| 摘 要： | 分析了电站汽轮机凝汽器的工作原理及过程,在此基础上建立了汽轮机凝汽器真空系统的简化数学模型,并推导了其相应的状态空间表达式。根据这一状态空间表达式参数不确定的特点,运用极点配置的方法进行了真空控制规律的理论设计与推导,提出了这个参数不确定系统渐近稳定的充分条件,求得了相应的状态反馈控制律。运用Matlab语言,对所设计的凝汽器真空控制律进行了数值仿真研究。仿真结果表明,所设计的控制律具有良好的控制效果。

| Abstract: | On the base of analyzing the working principle and process of the steam turbine condenser in power plant,a simple mathematical model of the vacuum system of the condenser is constructed,and its state space representation is deduced.Considering the uncertainty charac- ter of the parameters in the state space representation,the vacuum degree control law is designed by means of robust pole assignment tech- nique.A sufficient and necessary condition for the system with parameter uncertainty is presented,and the state feedback control law is ob- tained.Numerical simulation is offered and the simulation results show that the designed control law has good performances. |
