| Abstract: | This paper proposes an adaptive fuzzy controller based on plant's characteristics. The fuzzy controller first judges the plant's characteristics, and predicts the needed control energy. Then the controller dynamically changes the fuzzy sets range to adapt to various plants. Dynamic performance and stability are realized in the transient process and the steady state of the step response, respectively, to satisfy both demands. The paper presents a sufficient condition for the stability of the control system, which is realized by justifying fuzzy sets range of control variable. |
