Robust observer–based control for TS Fuzzy models Application to vehicle lateral dynamics
Résumé
This paper deals with the observer based robust
control design problem for TS fuzzy systems with time-varying
uncertain parameters. Sufficient design conditions of the fuzzy
observer and the fuzzy controller are first proposed. Due to the
use of Young relation, and the cone-complementary, the nonconvex
and Bilinear problems are then converted into convex
optimization one with LMI constraints. Controller and observer
gains are obtained under ℒ2-bounded disturbance and ℒ2-norm
input constraint by set feasible solutions of LMI conditions. The
effectiveness of the proposed fuzzy controller and fuzzy
observer design methodology is finally demonstrated through
numerical simulations on vehicle lateral dynamic model.
