摘要
尽管模糊控制技术适合于控制具有非线性和不确定性的对象,但常规的模糊控制系统缺乏自适应能力,限制了模糊控制技术的广泛应用。该文针对PID型模糊控制器,首先研究了模糊控制器相关参数与控制系统品质之间的关系,在此基础上,进一步提出了该类模糊控制器的参数校正方法,从而使所提出的模糊控制系统具有一定的自适应能力。论文最后将文中的自适应模糊控制方法应用到锅炉过热蒸汽温度控制中,取得了良好的控制效果。
Although the fuzzy control technique is fit for controlling non-linear and uncertain processes, the conventional fuzzy control system lacks self-adjusting ability, which restrains clearly the fuzzy control technique for widely application. Firstly this paper studies the relation between the adjusting scale factors and the control performance for the PID type fuzzy controller, and then proposes a method for tuning parameters of the PID type fuzzy controller, which makes the control system proposed in the paper have definite adaptive ability. Lastly the adaptive fuzzy control method proposed in the paper is applied to control the superheat steam temperature of the boiler, and the practical control effect is satisfactory.
