In this paper, we present a new fuzzy logic con-troller (FLC) for discrete-time systems. All the deci-sion rules of FLC are automatically generated by the Lyapunov stability criterion. The proposed control scheme can be easily derived with minimum informa-tion of the controlled plant. Furthermore, the fuzzy inference scheme can successfully be applied to stabi-lize the nonlinear discrete-time systems. We intro-duce three discrete-time systems, including a linear plant, a nonlinear plant, and a delayed plant, to demonstrate the effectiveness of the proposed FLC.
