In chapter four , problem about parameters of gpc on - line tuning in frame of satisfactory control is researched , and a satisfactory model for multi - parameters on - line tuning is defined , and proposed a formula based on grade conception and one - dimension searching method . it ' s shown that the system ' s performance can be improved by this approach 對多參數調整優化問題給出了滿意優化模型,并且對由此形成的多變量尋優問題引入了梯度的概念和一維搜索的方法給出了該多參數尋優問題求解迭代公式的杜十模糊btai與模糊約柬的浦意優化控制向量形式。
