Application of Advanced Genetic Algorithm in the Global Optimal Design of Permanent Magnet Generator in Automobile

The simple genetic algorithm is introduced at first. On the basis of many strategies to selector operator, crossover operator and mutation operator, the advanced genetic algorithm sufficiently considers the global optimum by generating new individuals in each generation, which guarantees the population´s multiplicity and accelerates the evolved speed. The optimal design of permanent magnet generator in automobile based on advanced genetic algorithm is explored in this paper. We adopted the permanent magnet as the main excitor, and electric excitation as the auxiliary excitor, a mathematical model of the generator is set up. The result shows that the advanced genetic algorithm could be applied well in the automobile permanent magnet generator. It satisfies the reliable constant voltage of the generator.
