The basic concept of granule and consistent covering granule are introduced. The related theorem of consistent covering granule is deduced. The certainty and likelihood of the covering granule based on covering fuzzy theory is proposed. The method of qualitatively and quantitatively describing emotional model of the PAD is constructed using granular model based on consistent covering fuzzy theory. Finally, the examples demonstrate that the proposed methods can describe the emotional granules and non-typical emotions in the emotional model of the PAD effectively.
