【摘要】 针对压水堆蒸汽发生器的水位控制提出了一种分层自适应模糊控制方案。该方案中,2个模糊控制器分层连接,每个模糊控制器均采用典型模糊控制单元,使得模糊规则个数和可调参数个数大大减少,便于在线学习和实时控制。文章分别给出了分层模糊控制器的解析表达式及可调参数的在线学习方法。在压水堆快速加负荷和突然甩负荷的仿真实验中,该方案与PID控制相比,响应快,超调量小,振荡小。更多还原

【Abstract】 In this paper, a hierarchical adaptive fuzzy control scheme is proposed for steam generator level control of nuclear power plants in pressurized water reactors. In this scheme two fuzzy controllers are connected hierarchically. Every fuzzy controller is a typical fuzzy control unit. Thus there are less fuzzy rules and adjustable parameters, which are easy to be modified on-line. The output expression of the hierarchical fuzzy controller and the modification algorithm of adjustable parameters are presented, respectively. The simulation results show that our scheme has better performance than variable gain PID control.更多还原
