Abstract/Description
This paper describes the fuzzy logic based robust pole-placement controller for the buck converter working in Continuous Conduction Mode (CCM). The converter operates at a switching frequency of 500 KHz. Pole-placement controller does not show good robustness to the load variations and the change in supply and reference voltages. In order to improve the static and dynamic properties, pole-placement controller supported by decomposed PID fuzzy algorithm is investigated. The performance of both the controllers, pole-placement and optimal pole-placement, is compared and conclusions are drawn. It will be shown that optimal control shows better dynamic performance. MATLAB/SIMULINK based simulation results validate the design.
