Comparison study between the terminal sliding mode control and the terminal synergetic control using PSO for DC-DC converter

DC-DC converters are widely used as reliable power source for many industrial and military applications, computers and electronic devices. Several control methods were developed for DCDC converters control mostly with asymptotic convergence. Sliding mode, 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. 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 sliding mode control performance, that which demonstrate the effectiveness and feasibility of the proposed control method.
