Abstract: We propose a new method of controller design for a buck-boost type dc-dc converter in this paper. An optimisation model for the controller design is developed and solution is sought through a novel optimisation algorithm named as queen-bee assisted genetic algorithm (GA) which combines standard GA with evolution of queen bee in a hive. Computed and measured results suggest that the new algorithm converges to best designs on a limited number of iterations.

Keywords: buck-boost converters; PID control; controller design; queen bees; genetic algorithms; dc-dc converters.
