摘要: This paper presents the,optimal design of the magnetic microactuator using the genetic algorithm. The magnetic microactuator is composed of an enclosed core and a permalloy plate to form a closed magnetic circuit. The present design allows the area of the magnetic poles to be optimally enlarged and achieve a maximum force generation. To obtain the optimal geometry and maximum force, the genetic algorithm (GA) which is a robust, stochastic search method modeled on the concept of natural section and evolution is proposed. To increase the search efficiency of the GA, strategies like population-elitist scheme, fitness scaling, and operator probability adaptations are used. The simulation results indicated that a dramatically improvement in generating magnetic force, that has the potential to enhance the actuating aspect in MEMS applications.
