【摘要】:KM降階算法是目前區(qū)間二型模糊集合常用的降階算法,針對其效率低、難以用于實時辨識與控制的缺點,提出了一種簡化的區(qū)間二型模糊系統(tǒng)辨識方法。該方法采用二型T-S模糊模型,前件參數(shù)為區(qū)間二型模糊集合,后件參數(shù)為普通T-S模糊模型形式。二型T-S模糊模型的解模糊化采用簡化的降階算法,提高了模型的辨識效率,可用于實時辨識與控制。仿真實例表明,所提算法在不降低辨識精度的情況下能夠有效提高辨識效率。
[Abstract]:KM order reduction algorithm is a commonly used order reduction algorithm for interval type 2 fuzzy sets. In view of its low efficiency and difficulty in real-time identification and control, a simplified identification method for interval type 2 fuzzy systems is proposed. The second type T-S fuzzy model is used in this method. The former part parameter is interval type 2 fuzzy set, the latter part parameter is ordinary T-S fuzzy model form. The de-fuzzification of the second type T-S fuzzy model adopts a simplified order reduction algorithm, which improves the identification efficiency of the model and can be used for real-time identification and control. Simulation results show that the proposed algorithm can effectively improve the identification efficiency without reducing the identification accuracy.
