The paper proposes a new development method for a Takagi-Sugeno PI-fuzzy controller meant for a class of plants applicable to the fields of electrical drives or servo systems. The developed fuzzy control systems are quasi-optimal in terms of some quadratic performance indices defined in dynamic regimes with respect to the step modifications of the reference input and of four types of disturbance inputs. The method is validated by a case study together with digital simulation results that can correspond to the speed control of a servo system.
