A design method of stable fuzzy controller on symbolic level for dynamical systems

Fuzzy inference has a multi-granular architecture consisting of symbols and continuous values, and this architecture has worked well to incorporate experts' know-how into fuzzy controls. The symbolic stability analysis of fuzzy control systems has been developed. However, this conventional analysis has not been applied to dynamic systems with state variables. This paper presents a design method of stable fuzzy controller using symbols applicable to dynamic systems.
