Chaos control of boost converter via the fuzzy delayed-feedback method

Boost convertor is utilized to increase amplitude of DC voltage with a high efficiency. In order to reach a desired output voltage, converter parameters are changed accordingly. These variations in the reference current may cause chaos and bifurcation in convertor dynamics which disrupt convertor functionality. This paper presents a new fuzzy delayed-feedback chaos controller for controlling boost converter. Using fuzzy controller improves the value of the inductor current and output of the converter. The resulted controller is also robust to small parameter variations of converter.
