Sintonización de una ley de control difusaproporcional retardada para estabilizar una clase de sistemas no lineales

In this paper, a method to tune a fuzzy proportional retarded (PR) control law for stabilizing a class of nonlinear systems is proposed. The stability of the nonlinear system is guaranteed through the stability of its Takagi- Sugeno (T-S) fuzzy model with feedback fuzzy PR controller. The tuning of the fuzzy PR control law has been addressed in the frequency frameworkusing D-partition method. Without loss of generality, the obtained theore- tical results are exemplied on a car-pendulum system. The performance of the control proposed here is compared with a classical parallel distributedcompensation (PDC).
