Abstract：A formal model of emotional agent is presented to make an agent have the ability of handling emotions. Three sub-models, agent's mental state model, agent's mental state update model and the final emotional agent model, are defined progressively on three levels. By the theoretical update process axioms of several basic emotions, the model is proved to sufficiently embody emotional agent's essential characteristics and running mechanism. It has strong ability of representation and can be easily extended, which provide theoretical foundation for the construction of emotion rule base that supports emotion reasoning. The specific emotion update process and architecture of emotional agent are described. Simulation results show that the emotional agent can elicit emotions properly and make more intelligent decision, which proves the validity of the proposed model.
