Genetic Algorithm based PI controller for Negative Output Elementary LUO converter

The Negative Output Elementary Luo converter is a newly developed DC-DC converter. Due to the time-varying and switching nature of the above converter, its dynamic behavior becomes highly non-linear. Conventional controllers are incapable of providing good dynamic performance for such a converter and hence optimized techniques have been developed to tune the PI parameters. In this work, Genetic (GA) Algorithm is developed for PI optimization. Simulation results show that the performances of GA-PI controller are better than those obtained by the classical ZN-PI controller.
