Abstract: This paper,first,decomposes the pension finance system into three subsystems;then by two-layer fuzzy comprehensive evaluation method gives a discription of normality of this system;at last establishes a new model of fuzzy feedback control for those pension finance systems of lower normality,so as to coordinate the internal operation objectives and mechanism of three subsystems and to get a harmonic state of the normal system.

Key words: Pension finance system, fuzzy comprehensive evaluation, fuzzy feedback control
