Abstract

With dramatic advances in electronics, electronic control has been increasingly applied to control based on sensors and actuators and improved energy efficiency and performance. With increasing system complexity, however, time required to develop the system controller has increased. To automate electronic controller design, we apply evolutionary hardware, starting with the targeted air-conditioning system and task definition, followed by the framework of applying a genetic algorithm to controller design automation, focusing on chromosome coding. We then present the fitness function we use to develop the air-conditioner controller automatically. Evolutionary simulation verified the feasibility of our framework.
