Stability Analysis of T-S Fuzzy System Based on Observers
Ning Li · Acta Automatica Sinica · 2003
A new way to analyze stability issues of T-S fuzzy system based on observers is investigated. A T-S system based on observers is regarded as the integration of a dominant subsystem and its interactive systems. The control law is a kind of switching control. Stability condition and design algorithm of the fuzzy system based on observers are devised using the vector Lyapunov function approach for partly observable premise variables. Corresponding conditions can also be obtained for two cases with respect to observable premise variables and unobservable ones. An example is also given.
