针对压水堆核动力装置蒸汽发生器的水位控制提出一种分层模糊自适应控制方案。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。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。在快速加负荷和突然甩负荷的仿真实验中 ,该方案的控制效果明显优于已有的变参数 PID控制 ,验证了该方案的有效性。
A hierarchical fuzzy adaptive control scheme is proposed for water level control of PWR nuclear power plant steam generator. In this scheme, two fuzzy controllers are connected hierarchically. Each fuzzy controller adopts a typical fuzzy control unit, which greatly reduces the number of fuzzy rules and the number of adjustable parameters, and facilitates online learning and real-time control. The analytical expression of hierarchical fuzzy controller and the online learning method of adjustable parameters are given. In the simulation experiment of rapid loading and sudden load rejection, the control effect of this scheme is obviously better than the existing variable parameter PID control, which verifies the effectiveness of this scheme.
