DC/DC converters fuzzy control

This paper aims to illustrate the use of a sophisticated methodology, based on system simulation techniques, to design a fuzzy controller for a DC/DC converter. The goal of the control is to stabilize the voltage output of the switching regulator against the load and parametric variations for a flyback topology. This system is characterized by being unstable in closed loop configuration. Robustness and high performances art requested to the control law especially for high power systems (more than 200 Watt). In order to obtain a good cost/performances ratio, the rules and the related membership functions have to be implemented via an analog dedicated solution capable to obtain an elevated number of FIPS (fuzzy inference per second)
