Comparison of PID and Fuzzy Controlled DC to DC Converter with Inductor Resistance

The DC-DC boost converter reveals highly non-linear and non-minimum phase properties, is very diffic ult task to design a controller that is healthy against load variation. For this purpose a Fuzzy PID Contr oller is proposed to control DC-DC boost converter which has a practi cal inductor and a series resistance. A balancing P roportionalIntegral-Differential (PID) controller to the paral lel-damped passivity-based controller PD-PBC is als o proposed for removing the steady state error even though the par asitic resistance. MATLAB simulations are performed under step changes and load perturbations to measure the impro vement in performance of the proposed approach.
