Robustness of fuzzy logic control for an uncertain dynamic system
Soo Yeong Yi, Myung Jin Chung · IEEE Transactions on Fuzzy Systems · 1998
Based on the similarity between prevalent fuzzy logic controllers (FLC) and the conventional robust controller, i.e., the variable structure controller, control theoretic analysis of a fuzzy control system is presented in the sense of Lyapunov. As well as the robustness of the fuzzy control system against uncertainties of a controlled process, this analysis gives an account of the relationship between control performance and the design parameters of the FLC, which has been obscure in the theory of fuzzy control.
