摘要： 采用一种建立在连续输入输出论域上的模糊控制器，避免了普通模糊控制器由于论域的离散化而存在的量化误差。通过采用分级模糊控制的方法进一步提高了系统的控制精度和收敛品质。同时还给出了一种自适应控制算法，利用它可以调整模糊规则以适应系统的时变性。利用该文的模莫糊控制器对典型非线性时变系统-VVVF液压电梯的实时控制结果表明；这种模糊控制器鲁棒性好，控制精度高，自适应能力强,具有很高的实用价值。

Abstract: Based on continuous I/O domain, fuzzy controller can avoid scalar error. System precision and astringency is improved by using multilevel fuzzy control. An adaptive control algorithm is given to adjust fuzzy rules to adapt system change. Result on typical non-linear system -VVVF hydraulic elevator has shown its good robustness, high precise and strong adaptive ability.
