Simulation and Analysis power Converter buck-boost by Fuzzy Controller

In this paper, Simulation and Analysis DC-DC Converter by Fuzzy Controller is investigated. Based on a qualitative description of the system to be controlled, fuzzy controllers are capable of good performance, even for those systems where linear control techniques fail, e.g.when a mathematical description is not available or is in the presence of wide parameter variations. The presented approach is general and can be applied to Buck–Boost dc–dc converter topologies. Controller implementation is relatively simple and can guarantee a small–signal response as fast and stable as other standard regulators and an improved large–signal response. Simulation results of Buck–Boost converter show control potentialities.
