【摘要】 本文针对控制阀粘滞特性而引起的回路振荡现象,提出了一种改进的PI控制方法,并将改进的PI控制方法转换成模糊控制经验,采用模糊控制克服回路中控制阀粘滞特性。最后在Matlab Simulink平台上,通过设计S函数,实现了控制阀粘滞特性模块和改进的PI控制器,使用模糊控制工具箱实现了模糊控制器的设计,在此基础上分析了在扰动存在的情况下两种控制方法的有效性。更多还原

【Abstract】 In this paper, an improved PI control method is developed to eliminate oscillations in control loops caused by valve stiction. The method is converted to fuzzy control rules which are used in fuzzy controller to compensate stiction. Finally, based on Matlab Simulink platform, the stiction model and the improved PI controller are implemented by using S-function and fuzzy controller is implemented by using fuzzy control toolbox. The effectiveness of the two proposed compensation methods is demonstrated by simulating under disturbances.更多还原
