Abstract: This paper proposes a Takagi-Sugeno (TS) fuzzy regulator design methodology for nonlinear dynamic systems. The Linear Quadratic Regulator (LQR) and Pole Placement (PP) techniques are combined in a TS fuzzy structure in order to guarantee an optimal controller with satisfactory transient response based on poles allocated properly. The definition and analysis of the multiobjective feasible region, considering the influence of the desired poles on the weighting matrices Q and R in the quadratic cost function, are presented. Lyapunov based stability analysis and simulations results on fuzzy regulator design for a robotic manipulator illustrates the efficience of the proposed methodology.
