摘要

The paper presents a design technique for robust PID controllers for Inductance Capacitance Inductance-T network (LCL-T), Capacitance Inductance Inductance-T network (CLL-T), and Inductance Inductance Capacitance—T network (LLC-T) Series-parallel Resonant Converters. The Series-parallel Converter controllers design is based on Bacterial Foraging Optimization (BFO). A BFO algorithm is employed in order to obtain the controller parameters assuring enhanced step response performance criterion. Simulation results of the designed controllers are compared with that of classical controllers whose parameters are adjusted using Ziegler-Nichols technique. Results signify the superiority of the proposed technique over the classical method. Experimental measurements of system performance validate the proposed technique and highlight its practicability.
