On the stability of T-S fuzzy control for non-linear systems

Zoe Doulgeri, J.B. Theocharis

Resum


This work concerns the stability analysis of a non-linear system controlled by a fuzzy T-S control law. It is shown that the closed loop system is in general expressed by a T-S fuzzy system composed of rules with affine linear systems in their consequent parts. The stability of affine T-S systems is
then investigated for a special case using as an example the regulation problem of a single link robot arm. Stability conditions are derived using the indirect and direct Lyapunov method and simulation results are presented.
