Summary: | 碩士 === 國立中央大學 === 機械工程研究所 === 97 === In this study, a stabilization problem for continuous-time fuzzy systems
subject to multiple time-varying delays in both state and input variables is addressed.
The main objective is to design a stablilizing controller that stabilizes the aforementioned delay system.
Based on Lyapunov-Krasovskii functional and P''olya theorem, sufficient stabilization conditions are stated in terms of
LMIs. Therefore, stabilizing controllers can be obtained easily with existing convex algorithms. Unlike existing methods,
polynomial theory is used to deal with input-delay term since this delay term introduces
an additional summation after defuzzification.
Lastly, three examples are given to illustrate
the advantages of the proposed machinery, yielding more relaxations when compared to existing methods.
