A fuzzy logic controller with fuzzy scaling factor calculator applied to a nonlinear chemical process
A combined fuzzy controller, consisting of a conventional fuzzy logic controller (FLC) with a fuzzy output scaling factor calculator that modifies the scaling factor of the FLC, is proposed. The performance of this controller is compared to the performance of a PID controller and a conventional FLC...

| Summary: | A combined fuzzy controller, consisting of a conventional fuzzy logic controller (FLC) with a fuzzy output scaling factor calculator that modifies the scaling factor of the FLC, is proposed. The performance of this controller is compared to the performance of a PID controller and a conventional FLC for disturbance rejection in a nonlinear chemical process. The proposed controller maintains its robustness under conditions at which performance of the other controllers decay.<br>En este trabajo se presenta un controlador de lógica difusa (FLC) con factor de escalamiento de salida calculado por medio de lógica difusa. El rendimiento de este controlador es comparado con el rendimiento de un controlador PID y un controlador de lógica difusa estándar (FLC) para la compensación de perturbaciones en un proceso químico no lineal. El controlador propuesto mantiene su robustez bajo condiciones en las cuales el rendimiento de los otros se ve reducida. |
