Abstract: The establish of emotional model can let the computer be equipped with the basic identification and the ability to express emotion，and it has a wide range of applications in the harmony human-machine interaction.This paper has an analysis in human emotion，and proposes artificial emotion models.In order to more accurately express the evolutionary process of the human emotion model，we propose improved genetic algorithm to estimate the parameters of the model.In order to overcome premature convergence of real-coded Genetic Algorithms（GAs），we combines advantages of the two aspects of individual and population to propose a new crossover operator named Heuristic Weighted Crossover Operator（HWCO）.Simulation results show that the emotional model estimated by the algorithm is in line with the basic law of human emotion.

Key words: artificial emotion, crossover operator, evolution, Genetic Algorithms（GAs）
