Imitation of State Feedback Controllers by Fuzzy Linguistic Control Rules TA-7-2 = 1210
Yung-Yaw Chen, Jyh‐Shing Roger Jang · 1990
There has been much dispute on the role of fuzzy logic in the field of automatic feedback control. Modem control researchers have not yet been fully convinced of the functionality of fuzzy control bccause its structure and stability has not been rigidly defined and proved. In this paper, we imitate the pcrformance of a state feedback controller by using linguistic control rules, which is commonly used in fuzzy control. We argue that a fuzzy logic controller should be able to achieve a performance at least as good as a state feedback controller’s when properly designed. A simulation-based comparison between the state feedback controller and the proposed fuzzy logic controller is also performed.
