Fuzzy state feedback controller tuning for DC/DC converter

Although linear state feedback control is a classical scheme for converter control, fuzzy state feedback is rather rare but efficient. Nevertheless, there is no simple and efficient method for tuning. This paper presents a new, simple and robust method for the tuning of fuzzy feedback controllers with the help of experimental designs. There is no need of any adaptive procedure and system model, the number of parameters is reduced with respect to classical fuzzy controllers. This strategy is successfully applied to a type of DC/DC converter that have an under damped behaviour during step input response and hard parameters sudden variations.
