【摘要】 针对电站锅炉水位系统的特性,首先设计了几种PID控制器,将它们应用于一个实际锅炉水位系统来观察控制效果.理论及实验仿真说明,这类控制器难以达到理想的控制效果,从而提出了模糊控制的方案,设计了3种模糊控制器并进行仿真及讨论.通过对所述控制器的理论分析和仿真讨论,表明模糊控制系统能够满足较高的控制要求,是一种很有前途的控制方法.更多还原

【Abstract】 Design a PID controller,according to the characteristic of the water level in boiler of power station and bring it into application.Theoretic discussion and experimental simulations show that the controller could not meet the desired effect.Therefore,three kinds of controllers which have different constructions were designed based on the fuzzy control.A further research of the controllers was carried out.And found that the fuzzy control is much superior to PID control.Its practical effect is amazing and the application in industrial environments is promising.更多还原
