Robust fuzzy feedback linearisation controllers for Takagi-Sugeno fuzzy models with parametric uncertainties

A robust fuzzy feedback linearisation controller is proposed to stabilise the nominal fuzzy system, and a sufficient condition is derived to guarantee the stability of the closed-loop system with bounded parameter uncertainties. For the systems with bounded uncertain parameters, we can design a robust fuzzy controller by choosing the control parameters satisfying the robust stability condition. The design scheme is not a trial and error procedure and it provides us freedom of select the control parameters showing the desired characteristics. The simulation results are given to verify the validity and effectiveness of the proposed control scheme.
