Stochastic Optimization Methods Based Robust Control for DC/DC Buck Converter

This paper proposes an Adaptive Terminal Synergetic Control (ATSYC) as a control strategy for Buck DC-DC converter. A simple Adaptive synergetic control (ATSYC) technique for the buck converter that has a fixed switching frequency and zero steady state error. The responses of this controller is robust and its can be defined directly in the time domain. In addition, GA & PSO algorithms will be used to optimize controller parameters using an ITAE criterion. The proposed control scheme is evaluated in a simulation study of a buck converter indicating satisfactory overall performance with stability ensured through Lyapunov synthesis.
