除氧器、凝汽器水位控制中 ,被控对象具有滞后、大惯性、时变性、不确定性 ,而且其特性随负荷而变化 ,用传统的 PID方法难以进行有效的控制。运用 Fuzzy-PI复合控制系统对其进行了仿真研究 ,给出模糊控制方法与传统方法的比较 ,说明 Fuzzy-PI复合控制对该类对象的控制效果良好
Deaerator, condenser water level control, the controlled object has a hysteresis, high inertia, time-varying, uncertainties, and its characteristics with the load changes, with the traditional PID method is difficult to effectively control. Fuzzy-PI composite control system was used to simulate the simulation. The comparison between the fuzzy control method and the traditional method was given. The result shows that the Fuzzy-PI composite control method has a good control effect on this kind of object
