Fuzzy Characteristic Model Based Intelligent Adaptive Control for Aerospace Craft

The study on intelligent control for aerospace craft is the hot spot and emphasis in the international research field of spacecraft. Currently, there are some modeling and control methods proposed to implement the intelligent control for aerospace craft. Among them, characteristic modeling (CM) is an effective method. But, there are also some deficiencies in dealing with nonlinear system concerning aerospace craft. In this paper, for the sake of overcoming the deficiencies to implement the intelligent control for aerospace craft, fuzzy characteristic modeling (FCM) method is proposed by combining Takagi-Sugeno (T-S) fuzzy modeling and CM methods. The fuzzy characteristic model based overall fuzzy control law is also discussed while the local adaptive controller is designed through the golden section adaptive control feedback law and feed forward control law. In addition, the stability condition for the proposed fuzzy controller is also briefly analyzed. The proposed approach has been shown to be effective via an example.
