Adaptive non-singular terminal synergetic power system control using PSO

Abstract

DC-DC converters have been receiving great attention for their extensive use in a myriad of applications starting with basic calculators to photovoltaic systems to sophisticated weaponry. Several control methods were developed for DCDC converters control mostly with asymptotic convergence. Synergetic control are a proven robust controllers approach and will be used here in a so called terminal scheme to achieve finite time convergence thus enhancing the already established technique robustness. An adaptive non-singular terminal synergetic control approach to handle uncertainties is provided resulting in enhancing robustness as well as a better transient performance compared to terminal synergetic control. Lyapounov synthesis is adopted to assure controlled system stability. Furthermore, a PSO algorithm will be used to optimize controller's parameters using an ITAE criterion. Simulation of terminal synergetic control of a DC-DC converter is carried out for different operating conditions and results are compared to terminal synergetic control performance, that which demonstrate the effectiveness and feasibility of the proposed approach.
